September is an ideal time to explore the charming Greek islands, as the scorching summer heat gives way to milder temperatures and the tourist crowds begin to thin out. Embarking on a September island-hopping adventure will allow you to bask in the Mediterranean sun, soak up the rich history and culture, and savour the lingering warmth of summer before the cooler months set in.

Naxos

Submitted by Martina from Places of Juma

The island of Naxos is one of the true treasures of Greece and is an excellent suggestion for a stunning getaway in the month of September. Located in the Cyclades, this idyllic island is easily reached by flying or ferrying from Athens. Naxos has some of the most exquisite sandy beaches in the Cyclades and is best known for its abundance of sandy beaches. An enchanting atmosphere is created by the crystal clear turquoise water and the velvety soft sand. Especially, September weather is still warm and there are almost no people on the beaches.

Aside from its stunning beaches, there are plenty of more things to do in Naxos. With its whitewashed old town and a fascinating fortress called the Kastro, the seaside town of Naxos is a must-see. There is also the emblematic symbol of the island, the Temple Gate of Apollo. Located on a nearby peninsula, it is the most popular spot for taking stunning photographs. For an unforgettable experience, be sure to visit the famous Portara at sunset. In summer this attraction is full of tourists but in September it`s a great spot to visit without the crowds.

There are charming villages to explore in the mountainous hinterland of the island. Halki, Filoti and the marble village of Apeiranthos are especially charming and allow visitors to submerge themselves in the authentic atmosphere of the island. Especially in September, these places are so charming, calm and amazing for a visit. For a more adventurous experience, consider a quad bike or rental car tour to the remote north or the serene east coast of the island. At this time of the year, the traffic is calm and you'll discover quaint fishing villages and hidden beaches that will have you in awe.

Syros

by Steven from the Thorough Tripper

The island of Syros is the administrative center for all of Greece’s Cyclades Islands. Its main city Ermoupoli is the capital city of the South Aegean. Sounds like Syros could be a little boring, right? Not at all! Syros has a lot to offer and should not be overlooked when hopping around the Greek Islands. And September is the perfect time to visit Syros. I know from personal experience - we visited this charming island last September and loved every minute of it.

Syros is very unique when compared to its more famous Cyclades neighbors. You won’t find the classic Cycladic architecture of white cubist houses and flagstone alleys here. Instead, Syros features neo-classical European architecture and many of the streets are paved with white marble.

Also, given that Ermopouli was once the most important port city in all of Greece, you’ll find the mansions of former ship captains sitting atop its harborside cliffs.

One of the especially great sites on Syros is the medieval city of Ano Syros which sits high above Ermoupoli and spills down a steep hillside. It features narrow allies and stairways, amazing views across the Aegean, and is topped by a 13th-century church.

Plus Syros is not without its beaches and quaint fishing villages. The most popular of these - called Kini - is easily reached in 20 minutes by bus from the main port.

And it’s not only perfect weather and fewer tourists that make Syros a great Greek Island to visit in September. If you are a fan of animation, Ermoupoli hosts an international animation festival every September called Animasyros. It’s the largest animation festival in Greece and one of the largest in Europe. You’ll find free screenings and other events taking place at various venues throughout the city.
Here’s even more information on many of the great things to do on Syros.

Crete

by Simon of Backpack moments

Did you know that the first advanced civilization in Europe was the Minoans on Crete? They built impressive palaces complete with plumbing systems, frescoes, and gates, evidence of which you can still see near the capital Heraklion. The civilization prospered between 3000 BC and 1100 BC when a devastating earthquake and a volcano eruption wiped it out. Greece's largest island has had a colorful history as part of Ancient Greece, the Roman and Byzantine Empires, Venice, the Ottoman Empire, and since 1821 - part of Greece. To learn more about history, you can visit Heraklion Archaeological Museum.

Located in the southeast Mediterranean Sea, Crete is a wonderful destination year-round. The best month to visit Crete though is definitely September. As the sun becomes more forgiving and the masses of holidaymakers return to their home countries, Crete becomes a lovely place for a vacation. The average temperature is around a perfect 26C (79F) while the sea welcomes beachgoers with 23C (73F) water.

On Crete, you should explore the old towns of Chania, Rethymno, and Heraklion (don’t forget to visit Knossos - Europe’s oldest city!). Challenge yourself by hiking through the Samaria Gorge or Imbros Gorges enjoying the outstanding scenery. Top it all off by relaxing at some of the most beautiful beaches in the world - Elafonisi, Balos, and Preveli.

If you’re in Crete on the 13th and 14th of September, make your way to the smaller villages around Chania. There you can participate in The Festival of St Stavros, one of the most important Christian Orthodox celebrations on Crete. The central squares of villages like Maza and Aptera are transformed into open spaces for traditions and customs. There is course a lot of food (like Cretan cheese, bread, and cured meat) and drinks (especially tsikoudia, the Cretan variation of the alcoholic raki).

All in all, Crete is an eclectic island that offers a variety of things to do and is a superb holiday destination for September!

Ios

by Valentina from Valentina’s Travel Guide

If your idea of a vacation in Greece is spending your days relaxing at the beach and your evening in a small village where to taste Greek Food, Ios might be the perfect Greek island for you.
Ios Island is known to be a party island in July and August, but if you visit it in September, it turns into one of the quietest islands in Greece. Ios Island is pretty small; you can visit it in one day. It is connected by ferry (no airport on Ios) from Athens and the islands nearby. If you are considering island hopping, you can visit Ios after visiting Paros and before heading to Santorini.

Most hotels are on the hill around the main village of Chora or along the coast, so you will need transport to reach your accommodation from the port. You can use the local buses or rent a car to move around the island. If you decide to stay in Chora, the view from there is lovely, mostly at sunset, and to reach the most famous beach on the island, Paralia Milopotas, you can use the local buses that will take you there in only 5 minutes. Paralia Milopotas is a gold sand beach to spend days swimming, relaxing, and trying some water sports. With 20 euros, you can get two sunbeds and a beach umbrella and get your breakfast, lunch, and dinner delivered by the restaurants behind the beach that owns the adjacent beach area.

That means you don't need to leave your spot but can have all your meal while looking at the water. Having dinner on your sunbed while looking at the sunset is one of the most fantastic experiences in Greece and one of the best ways to end a wonderful day. A shop you must take advantage of on Ios Island is Mosenta Traditional Products of Ios, in the town of Chora. There you can find all the local souvenirs (mostly food), like Greek cookies, local thyme honey, olive oil soap, and much more.

Mykonos

by Soline On the Road Diary

Mykonos is an incredibly beautiful and vibrant Greek island, located in the Aegean Sea. With its white cobbled alleys, pristine sandy beaches, crystal clear water and wild nightlife, it's no wonder that Mykonos has become a popular holiday destination for so many people. That is precisely why you should visit Mykonos in September! Because it is a bit off-season, you will be able to enjoy Mykonos without the crowds of tourists.

The island gets very crowded between June and August. After a busy summer season, September feels like a fresh breath while still being animated and warm. The temperature in September goes from 20°C to 25°C (68°F to 77°F). You can enjoy swimming in the Mediterranean Sea, have swimming pools with incredible sunset views all to yourself and soak up the late summer sun.

This is also the perfect season to wander around in the picturesque villages of Mykonos. Start at Mykonos Town to see Little Venice, a collection of old white houses with colorful doors and balconies right on the edge of the sea.

Turn around and see the famous windmills of the Mykonos town’s hill. Then, get deeper into the island. Explore the peaceful villages of Ano Mera in the middle of the island, and Klouvas at the north of Mykonos. If you love exploring ancient Greek ruins, discover the archaeological site on Delos Island, located right in the south of Mykonos!

There is so much to see on the island that you will need at least 3 days in Mykonos.

Corfu

by Anna from Spain Inspired

If you're considering a trip in September to Greece, I'd definitely recommend taking a closer look at Corfu.

For one thing, September in Corfu offers seriously good weather. The extreme summer heat mellows, with temperatures settling in the mid-20s°C (around mid-70s°F). It’s warm enough to enjoy the island's (incredible!) beaches, yet cool enough to explore without breaking a sweat.
In addition, the peak summer tourist crowds have largely moved on by September. This means more space for you on the beaches and in Corfu's Old Town, shorter waits at local eateries, and a generally more peaceful atmosphere to enjoy the island's charm.

Post-summer months also often see a reduction in accommodation prices, meaning that September offers better value for your money. Hiring a car is also much easier and generally cheaper this month, which is a great option for exploring some of the island's more remote beaches.
At the same time, the vast majority of the main tourist activities are still running before winding down for winter. I'd recommend taking a boat trip to Paxos and the Blue Caves from Corfu, for example, as Gaios, the capital of the island, is honestly like a postcard, the color of the sea is spectacular (and the temperature is still perfect for swimming) and the boat won't be as packed as it is in July and August.
Ultimately, if you're after an island experience that's a blend of warmth, relaxation, and culture, visiting Corfu in September could be just the right fit.

Lesvos

by Cora from Inside Our Suitcase

Lesvos is the third largest Greek Island but is often overlooked by tourists in favour of islands and cities such as Athens, Santorini and Mykonos. However, if you’re looking for an authentic, traditional Greek vacation where time no longer exists, I highly recommend coming here.

There aren’t any Starbucks, McDonalds or high-rise hotels in Lesvos. In fact, quite the opposite. All the restaurants and charming apartments here are typically owned and operated by the locals and it’s this local sense of community that makes Lesvos the most repeatedly visited Greek island. In fact, many tourists I spoke to in Lesvos had been coming to the island for 20+ years and loved that the place never changed.

Despite a large volume of repeat visitors to Lesvos, the island is far from crowded. In fact, quite the opposite. Given the limited number of accommodation options on the island and few direct flights from European cities, Lesvos really does remain a hidden gem.

So much so that the small number of repeat tourists often know each other, the locals, and their family members personally. During my most recent visit to Lesvos, a tourist actually attended the funeral of a local resident who they had known for more than a decade. That’s how much of a community spirit there is here.

September is actually the best time to visit Lesvos as there are two world-renowned festivals on the island at this time. First, there is the International Eressos Women’s Festival which is held in the charming coastal town of Eressos over a period of 10 days. Alongside this, there’s also the Lesvos Euphoria International Festival which aims to promote Lesvos for its alternative character and unique energy through the advancement of mental and psychological health.

Agistri

by Annie from Your Friend the Nomad

Often overlooked, Agistri is a gorgeous Greek island just an hour away from Athens via ferry. Most visitors are locals from Athens, and the island never gets too crowded, especially not in a month like September.

Those who do discover Agistri are in for a treat! The quaint island can easily be explored via bike, scooter, car rental, or even foot—if you’re up for an adventure. The island’s charming villages feature a slow way of life that hasn’t been disrupted by tourism like Greece’s most popular islands.

The island’s turquoise-blue water beaches are pristine and uncrowded. The island’s most well-known beach is Chalikiada, which is just a short walk from the main ferry port. To reach the stunning secluded beach, visitors must hike down a cliff—it's a bit of a scramble, but it’s worth it! But be warned, Chalikiada Beach is known as a nude beach, so you might see a little extra skin!

There are just a few small villages in Agistri, including Skala, Chalikiada, and Limenaria. Most visitors choose to stay in Skala, which is where the main ferry terminal is located, and where most of the island’s restaurants and hotels are.

You can take a car on the ferry to Agistri from Athens, though most visitors opt to get around the island by foot or bike since it's so small. There are several shops in the main towns that offer bike rentals at a reasonable rate.

In September, Agistri’s average temperatures range from 67-83 F, making it a pleasant place to visit. Some of the best things to do on the island in September include beach hopping, biking around the island, renting a boat for the day, taking the ferry to nearby Ageina or Athens for a day trip, and enjoying a drink at a beachfront bar.

Lefkada

by Kelli from the Vanabond Tales

September is the perfect time to visit the Ionian island of Lefkada in Western Greece. The combination of temperate climate, fewer crowds, affordable prices, and local celebrations make September arguably the best time to experience this Mediterranean gem.

September is a warm and sunny month in the Greek Isles, but without the intense temperatures of July and August as summer begins to recede. September in Lefkada enjoys an average temperature of between 13 and 22. This means a better climate for exploring the multitude of outdoor activities available throughout the mountainous island.

One of the key draws of Lefkada in September is the more relaxed atmosphere as the summer tourist crowds start to dissipate. As the peak summer season tapers off, you can enjoy the island's stunning beaches and picturesque villages without the throngs of other visitors. Beyond a more relaxed atmosphere, you’ll also find prices for accommodation and attractions start to come down. Furthermore, as summer winds down, the locals begin to relax after the busy season and hyper-tourism makes way for authentic island life.

With the island being returned to the locals, this is a time of festival and cultural celebration with the Lefkada folklore dancing festival and the Apolpena local wine festivals both taking place at the beginning of September.

The waters of the Mediterranean surrounding Lefkada remain warm and inviting in September, making it an excellent time for swimming and water activities. Whether you're a fan of lounging on the beach, trying your hand at the many water sports on offer here, or exploring the island's captivating coastline, the weather and sea conditions are in your favor.

Overall, the milder weather, lack of crowds, and more authentic experience make September the perfect time to explore the breathtaking Lefkada.

Tinos

By Monique at Trip Anthropologist

Tinos Island is an island in the Cyclades island chain, 3 hours from Athens by fast ferry and only 3 minutes from Mykonos. It is most spectacular in Spring and Fall when wildflowers and colored foliage transform the ancient hiking paths into lush wild gardens.

September sees the island still 100% open for tourism, but without the summer crowds, and especially without the daytrippers from Mykonos, Naxos, and Paros. Tinos is the best island in the Cyclades for hiking and the average maximum daytime temperature in September hovers around 73-75 degrees Fahrenheit, or 23-25 degrees Celsius.

The Meltemi winds continue to blow across the Cyclades islands in September so there will usually be a warm breeze which is another reason that hiking Tinos is perfect during this month.

Accommodation prices across the island, especially away from the southern beach areas, are falling but tavernas, beach bars, and mountain cafes remain open. With the possible exception of Halki (Chalki) on nearby Naxos Island, the mountain village of Pyrgos is perhaps the most beautiful mountain village in the Cyclades.

Tinos has a wonderful and strange phenomenon dotted through its amazing landscape - hundreds of Venetian dovecotes that are highly decorated along with the abandoned windmills, goats, and strange rock formations, add to the feeling of discovery you get when exploring this island by foot.

The traditional decorative arts of Tinos are alive and well and you'll find decorative plaques on walls and embedded into paths in rural villages. Marble crafts are particularly important here and the indigenous designs found on dovecotes are echoed in the homes and buildings you'll find scattered over the island.

Driving around Tinos is simple - high narrow mountain roads are virtually deserted except for goats and you really feel that you have escaped to your personal idyllic Greek island. Don't miss the opportunity to wander alone through this enchanting landscape in September.

Santorini

Contributed by: Lavina D’Souza of Continent Hop

With beautiful white houses and azure blue waters, Santorini is a treat for the eyes and the soul. This island is one of the best holiday destinations of all time.

September follows the peak season; therefore, it is still buzzing with travellers. It is slightly better than the peak months. The crowd does not completely vanish in September, although it is slowly decreasing. So if you want a tranquil vacation, you may visit at the end of the month.

The weather is great with temperatures between 20 and 30 degrees and the island is sunny with bright clear skies. There are slight chances of rainfall so make sure you check the weather forecasts and plan ahead.

You should definitely start your trip by exploring Fira, the city’s capital. It is a small but wonderful capital with beautiful views and picturesque churches. You can also hike from Fira to Oia through the Caldera trail. You will find some great spots for your Instagram pictures along the way. I recommend heading out early to avoid strong heat.

Watching the sunset in Oia is at the top of the list for anyone who is visiting Santorini. The most famous pictures of Santorini are mostly of the sunsets in Oia. it is a wonderful experience and it may be crowded during sunset but you can arrive early and pick out a good spot to sit and enjoy the sunset. If you are looking for something more private, you can also book a restaurant overlooking the beach. There are also a lot of other things to do in Oia such as exploring the churches, blue domes and much more.

You can go for a swim in the sea as the water is warm and relaxing. You can even take a stroll along the shore while sipping on your favourite drink. There are a lot of restaurants which serve delicious Greek food. You must try Greek salads, Moussaka, Keftes and much more along with Greek wine of course! If you are a wine admirer, you can even head for some wine-tasting events.

If you are an adventure seeker, you can hike to the top of the Santorini Volcano to enjoy beautiful panoramic views. Besides this, your trip won’t be complete until you sail around Santorini. You can book a tour and many tours will halt for a while for you to take a refreshing dive into the ocean.

Santorini in September may not be a little crowded but it is surely exciting. You can head out for fun activities or just lounge on the beach and enjoy the sunset. Santorini has a lot to offer and you will always crave more of it.

Rhodes

by Josh A Backpacker's World

One of the best Greek islands to visit in September in September is Rhodes. Rhodes is a special place to visit, and despite the wildfires of the 2023 summer, it's still a really popular destination to visit.

September makes for a great time to visit Rhodes, as the crowds have died down enormously. Rhodes is most popular amongst families and students, so by visiting in September, all of the kids will be back to school and the students will be back in university, leaving Rhodes considerably less busy.

But even though the crowds disappear, the good weather does not. You can expect an average temperature of 24°C on Rhodes in September. It's very pleasant, and much more bearable than the high forties of July. You'll definitely get a tan visiting in September!

In terms of things to do on the island, Rhodes has an abundance of history, just like many of the Greek islands. There are lots of ancient ruins to check out and explore scattered throughout the island.

The most popular is probably the Lindos Acropolis for ancient Greek ruins, but the Palace of the Grand Master of the Knights of Rhodes is the main attraction on Rhodes. It's a medieval castle dating back to the 7th century, and it's in extremely good condition. It's fascinating to see and learn about, and the views are incredible too. Seeing the castle is a must-do.

Another example of the rich history is the Medieval City of Rhodes which is a UNESCO World Heritage Site. It's just part of the city of Rhodes and is just like the "old town" of any other city. But exploring it is a must-do. It's up there with exploring Rome!

All in all, Rhodes is a must-visit, and there's no better time than in September.

Sifnos

by Robyn from Two Empty Passports

Sifnos is a gorgeous Greek island in the Cyclades full of traditional towns, gorgeous scenery, and stunning beaches. But what capitulates Sifnos above the rest is its mouthwatering cuisine.

If you’re a food enthusiast, September is the perfect month to visit Sifnos. Nicknamed the Foodie Island, every September, the hilltop town of Artemonas hosts the Festival of Cycladic Gastronomy. This appetizing event honors Nikolaos Tselementes, the renowned Greek chef who mastered the fusion of traditional Greek flavors with modern cuisine.

Each Cyclades Island showcases its unique recipes and traditional cooking at dedicated booths during this 3-day event. Come and enjoy the festive music, traditional dances, and amazing views of the island from adorable Artemonas, the highest town on Sifnos. Entrance and food tastings are free of charge. So you can sample appetizing slow-cooked lamb marinated in wine and dill, crispy eggplant rolls, and finish it off with a traditional honey and cheese pastry. Indulging in Greek cuisine is one of the best reasons to visit Sifnos.

And that's not all Sifnos has to offer!

Spend your mornings hiking the beautiful, terraced landscapes, or wandering the narrow streets in the many towns throughout the island. The picturesque village of Kastro is full of white houses with brightly painted shutters, ideal for a morning cappuccino.

Head to Platos Gialos for a delicious seaside lunch at Votsalo Creperie & Pizzeria, then rent a lounger for a relaxing afternoon. The crystal clear water is perfect for swimming and the surrounding mountains make this the ideal town for relaxation.

Thankfully, Sifnos is not as touristy as other islands, even during peak season. And September is a fantastic time to visit as the weather is warm and dry. Average daytime temperatures range from 22°C to 28°C (72°F to 82°F) and the sea is still perfect for swimming and water activities.

Elafonisos

by Alexandra from The Alternative Travel Guide

Elafonisos Island is a really great place to visit in September and is one of the secluded and quiet Greek islands. First off, the weather is pretty sweet. It's not crazy hot like it can get in the peak summer months. You can still enjoy the awesome beaches and outdoor activities without feeling like you're roasting in an oven.

Another advantage of visiting Elafonisos in September is the lack of crowds. September is like that chill time between the super busy summer and the quieter fall season. That means you can have those stunning beaches more to yourself. No need to fight for your own sandy spot!

It's like a tranquil oasis where you can unwind and forget about your worries. And speaking of your wallet, you might save a bit too.

You'll experience the island's culture and daily life in a more real way. Locals are often more relaxed and open to chatting when they're not swamped with tourists.

If you are a nature lover, Elafonisos Island's got you covered. Besides those fabulous beaches, there are hiking trails and stunning landscapes waiting to be explored. And September's comfy temperatures make it even better.

September and Elafonisos Island make a pretty awesome combo. It's like the perfect dessert after a fantastic Greek feast.

Milos

by Tamara Williams from My Elated Odyssey

One of the best Greek islands to visit in September is Milos. Known for having some of Greece's most unique beaches and landscapes, this island will leave you wanting to return.

September is an exciting month to visit Milos due to the religious festivals beginning in the summer months. Two popular festivals during September are the feasts of Agios Sostis in Provata on the 6th and Panagia Korfiatissa in Plaka on the 8th. There will be ceremonies in the morning, followed by traditional performances, feasts, and music.

The top attraction in Milos is undoubtedly Sarakiniko Beach. Many describe this beach as one that mimics the moon’s landscape from the white rock formations shaped by lava. This site is excellent for cliff jumping, sunsets, and general relaxation. Other phenomenal beaches worth a visit during September that a boat tour can reach include Kleftiko and Tsigrado. In addition, there are charming fishing villages that are worth a visit, including Klima.

Weather conditions in Milos during the month of September are pleasant. In fact, many locals state that September has the most favorable weather in the year. One of the best parts about the weather is that you won’t have to deal with the intense heat from July and August.

Instead, the island experiences sunny skies but with more favorable temperatures. On average, you can expect temperatures of 28°C (82°F) for the highs and 20°C (68°F) for the lows. These weather conditions allow you to relax on the many beaches and do the popular boat tours.
If you’re looking to escape the intense crowds that can be found in Santorini and Mykonos, then Milos is your best bet. Even in peak season, you won’t find shoulder-to-shoulder congestion, allowing for a comfortable vacation.

Hydra

by Ausra from The Road Reel

Located off the Eastern shores of the Peloponnese peninsula, in the heart of the Aegean Sea, Hydra is one of the best islands in Greece to visit in September. Only an hour by ferry from the capital Athens, Hydra is a beloved weekend getaway for locals and visitors alike who seek an easy day trip to experience laid-back Greek island life.

Hydra, one of the four main islands of the Saronic Gulf, is known for its picturesque harbor enveloped with dreamy white-washed red-roofed houses climbing steeply up the rolling hills. You don't need to rent a car to visit this Greek island, as it is cobbled streets are completely car-free and the main mode of ground transportation here is donkeys and horses. That alone will make you feel like you have travelled back in time. In fact, even bicycles or mopeds are not permitted on the pedestrian-only island.

The beginning of Fall is a golden window to visit Hydra and enjoy the best this pretty Greek island has to offer. The temperatures are mild and the crowds are significantly thinner than during the summer. Moreover, the chances of ferries being cancelled are also slim.

In Hydra, you can enjoy the lively port area watch the locals getting about their daily routines, and wander along the labyrinthine alleyways, where traditional houses with vibrant blue shutters stand as a testament to beautiful Greek architecture.

Moreover, if you are up for a swim in the turquoise waters that bathe the shores of Hydra, September is a perfect time to do so. You do not have to go far as some of the popular beaches are just around the corner from the port. Meanwhile, if you are looking for more tranquillity, there are many hidden beaches on the island you can get to by water taxi.

If you love hiking, September is an ideal time to tackle the island's scenic trails. Trek to Hydra's highest peak for panoramic views and go exploring the hidden chapels and monasteries that dot the landscape.

Lastly, if you decide to spend a night on this magical island, September is known for its beautiful sunsets. Head for heartful Greek food at Sunset Restaurant which as the name suggests is a perfect spot to see off the day.

Koufonisia

by Catherine Xu from Nomadicated

The Koufonisia Islands, often called the "Mykonos of the Little Cyclades," is an up-and-coming gem on any Greek island-hopping adventure. They are perfect for a September getaway, boasting some of Greece's finest sandy beaches. These small yet beautiful islands are easily accessible and return to a laid-back vibe as the summer crowds thin out.

September is a magical time to visit Koufonisia. The scorching summer heat mellows into a pleasant warmth, with temperatures hovering around a comfortable 71F-78F degrees. The seawater remains warm from the summer heat, and the days are mostly sunny, with a delightful breeze from the Aegean Sea in the evenings.

This Cyclades archipelago comprises three islands - Ano Koufonisia, Kato Koufonisia, and Keros, the latter being uninhabited due to ongoing archaeological excavations. Ano Koufonissi, the main island, is where the main amenities are, like hotels, restaurants, bars, and well-developed roads. On the other hand, September is perfect for adventurous souls to free camp on Kato Koufonisia and discover its hidden beaches.

What makes Koufonisia extraordinary are its incredible sandy beaches with clear turquoise waters. Unwind at Ammos, Fanos, Italiada, and Finikas; are some of the best sandy shores in Greece, quite rare when most others are rocky. And while you're exploring the coastline, take a refreshing dip in the natural pools or have a blast cliff-jumping!

You can easily get around on foot since the island is so tiny. But if you want to make exploring more convenient, rent a bike or hop on a boat taxi that takes you around and between islands. When the sun goes down, the island's nightlife comes alive. Have a lovely evening at one of the taverns in Chora, like the amazing Mikres Cyclades, where you can enjoy delicious Greek cuisine and great wine.

Even though Koufonisia is pretty popular among locals, it's not widely known to foreigners yet. That's why it stays relatively affordable even in the peak of summer. But during the shoulder seasons, the prices drop to at least half of what you'd pay during the busiest times.

Folegandros

by Melissa from A Solo Woman Traveling

If you are looking for one of the most authentic Greek islands to visit in September I have just the place! The lesser-known Greek island Folegandros is the ideal Greek island to visit in the month of September! While other islands such as Santorini, and Mykonos will be packed to the brim and overcrowded with cruise ships, you can get some peace and quiet on Foldegandos.

Folegandros is one of the western Cyclades located just an hour's ferry ride from Milos. You might have heard of the many things to do in Milos, but perhaps very little about Folegandros!? What makes Folegandros so special is the authentic village and the views of the Aegean Sea. If you stay in the Chora (main town) you will be high up on the cliff with access to the Church of Panagia.

Climbing to the top of the church of Panagia for the most spectacular view should be high on the to-do list. Access to the church is free and one of the most magnificent places to watch the sunset, if you can climb the 15 minutes uphill to get there. The weather in Folegandros in September can get upwards of 30 degrees Celsius and 86 Fahrenheit.

Folegandros in September is the perfect time to visit one of the many secluded beaches such as Galifos Beach. You can easily reach the nearby beaches in Folegrandros by bus! The main village in Folegandros is pretty small, but packed with restaurants serving up delicious Greek cuisine.

With an island as small as Folegandros, the perfect amount of days to spend here would be 3 nights. And, since September is the start of the shoulder season you should find better deals on accommodations.

For all these reasons and more, visit Folegandros in September!

Kos

by Maartje from The Orange Backpack

Kos, a Greek island nestled in the Aegean Sea, holds irresistible allure for travelers seeking a special September getaway. With a climate that boasts warm summers and mild winters, Kos is an ideal destination year-round, but September stands out as a prime time to visit.

September marks the sweet spot between the scorching summer and the quieter winter months, making it a special time to experience the island's charms. The weather during this period is a delightful symphony of balmy temperatures and gentle breezes, creating the perfect backdrop for exploration and relaxation. What sets Kos apart in September is the fewer crowds. As the summer crowds ebb away, Kos regains its tranquillity, allowing visitors to relish its beauty without the usual hustle.

The island's rich history and captivating attractions become even more accessible in September without the beating warmth of the summer days. Travelers can wander through Kos Old Town, also one of the most popular places to stay in Kos. It's where echoes of medieval times reverberate through ancient ruins and the Roman Odeon. The remnants of Asklepieion Kos offer a glimpse into the island's past, while the Embrós Hot Springs promise relaxation amidst natural splendor.

Nature lovers will find solace in Plaka Forest, while history enthusiasts can explore landmarks such as Antimachia Castle and Neratzia Castle, both standing as stoic reminders of bygone eras. With the convenience of a rental car, Kos unfolds its treasures at a leisurely pace, revealing hidden gems like the serene Agios Stefanos Beach or the breathtaking sunsets of Zia.

September on Kos radiates a unique charm, as the warmth of the locals combines with the decreased tourist presence to create an atmosphere of genuine hospitality. Whether unwinding on its inviting beaches or indulging in authentic Greek cuisine, the island is a must-visit among the Greek islands.
