A guide to spending summer in Greece

With picture-perfect coastlines, dreamy island getaways, and cities steeped in history, summer in Greece offers everything you’d hope for in a Mediterranean getaway. It’s the season for enjoying long beach days, exploring ancient landmarks, and wandering through storybook villages that look as if they were plucked from a postcard. Best of all, it’s the perfect time of year for swimming in the Aegean and setting out on an island-hopping adventure. This guide covers where to go to avoid the crowds, what to see and do, and how to make the most of your summer in Greece.

Why summer is the ideal time to visit Greece

Long, sun-filled days, warm turquoise waters, and almost no rainfall make summer one of the best times to explore the country’s iconic islands, coastlines, and ancient ruins. It’s the perfect season to swim near crystal-clear coves, hike to scenic overlooks, and plan romantic beachside dinners. Summer is also the peak of Greece’s lively festival season.

For travelers who love long days, warm nights, and life by the sea, it’s hard to beat the summer in Greece. Here are our top tips and recommendations to help you plan an unforgettable Greek trip.

Planning when to visit: average temperatures, climate considerations and variations

Summer in Greece starts in June and peaks in July and August. During these months, the days are long, dry, and hot. Temperatures in most parts of the country are between 85-95 degrees Fahrenheit (30-35 degrees Celsius) during the day, especially in the south and on the islands. The sea is warm and the skies stay clear, while the coastal breezes can make the heat feel more manageable, particularly on the islands.

Consider traveling in early June or at the end of summer in September for fewer crowds and more comfortable temperatures. The weather is still ideal for swimming and outdoor activities, but prices tend to drop. These shoulder season months are also great times of year to plan for a more meaningful, slow travel escape.

July and August are the country’s peak tourist season, and you can expect large crowds in popular island destinations like Santorini and Mykonos. If you plan to travel during this time, booking your ferries and accommodations ahead of time is advisable.

However, for summertime travel we’d always encourage venturing beyond the usual hotspots to smaller islands or under-the-radar towns, where you’ll find fewer crowds, a more relaxed atmosphere, and a chance to experience Greece at its most authentic—all while supporting a more responsible form of tourism.

Packing tips: summertime essentials and sustainability

When packing for Greece in the summer, light and breathable clothing is the way to go. Linen shirts and pants, cotton dresses, and comfortable walking shoes are all smart choices. The sun can be intense in summer, so don’t forget your sunglasses, sunscreen, and wide-brimmed hat.

If you’re planning to hike, bring sturdy walking shoes. You’ll also need to pack modest clothing that covers your shoulders and knees if any religious sites are on your itinerary. Greece’s northern regions can get cool at night, so a light jacket or sweater is worth having just in case.

To travel more sustainably, consider bringing a reusable shopping bag and a refillable water bottle. Many islands struggle with waste during peak season, so small habits can make a real difference.

Curbing overtourism: how to experience the magic of Greek summers responsibly

Islands like Santorini and Mykonos are undeniably stunning, but they’re often overwhelmed by tourist crowds in summer. If you’re looking for a more sustainable way to experience Greece, consider visiting nearby islands that offer more breathing space.

Stay in smaller, less touristy areas, book tours early in the morning or later in the evening, and choose locally owned accommodations to help ease the pressure on the local communities.

Must-visit destinations in Greece during summer

Luckily, you don’t need to follow the crowds to enjoy your summer. Some of the most incredible destinations in Greece are the ones you’ve never heard of.

Exploring the rich heritage of Athens

Athens is more than just a gateway to the islands. It’s a culture-packed capital where ancient history and modern life collide.

Start your adventure at the Acropolis, then explore lesser-known sites like Kerameikos or the Roman Agora. These landmarks bring the city’s history to life and give you the unique chance to marvel at thousand-year-old ruins nestled next to local neighborhoods.

At night, rooftop bars offer views of the Parthenon, while outdoor cinemas show films under the stars. Neighborhoods like Psirri and Kolonaki are perfect for a stroll, with plenty of spots to stop for an al fresco meal or drink.

If you need a break from the heat, spend a few hours in the National Archaeological Museum. You can also take a quick ferry to Aegina, a nearby island known for pistachios and traditional tavernas dotting the waterfront.

Responsible travel to sun-soaked paradise: Greek islands off the beaten track

For a summer filled with quiet beaches, charming towns, and a laid-back pace, skip the busy hotspots and head to the less-visited of Greece’s many islands.

Naxos is the largest of the Cyclades, known for its long sandy beaches, scenic hiking trails, and family-friendly atmosphere. It’s also a great place to try local cheeses and citrus liqueur. Milos is beloved for its striking coastline, colorful fishing villages, and postcard-worthy coves. If you’re feeling adventurous, join a kayaking tour to see the island’s unique rock formations and sea caves up close.

Food lovers should head to Sifnos, where classic Cycladic architecture and coastal trails meet one of the best food scenes in the country. For a slower pace, Ikaria is the perfect island to visit if you want to recharge. Here, you can spend your afternoons soaking in the natural hot springs.

On Paros, you’ll find picture-perfect towns like Naoussa and beautiful beaches and inland villages to explore at your own pace. Want something more off the beaten path? Check out Astypalea, a small butterfly-shaped island with a hilltop castle.

Discover the lesser-explored gems of northern Greece

Northern Greece is a great summer option if you’re looking to escape the heat and crowds. Often overlooked, this region is full of natural beauty and lesser-known cultural highlights.

One city worth adding to your northern itinerary: Thessaloniki, Greece’s second-largest city. It boasts excellent restaurants, historic sites, and a lively waterfront promenade. It also makes a convenient jumping-off point for trips to Mount Olympus or the nearby wine country.

Just a short drive from Thessaloniki, Halkidiki offers beach lovers a peaceful alternative to the islands, with beautiful beaches and sheltered bays. Head to Sithonia (the middle peninsula) for boat tours and lazy days swimming in the crystal-clear waters.

For outdoor enthusiasts, Zagori is a must. This mountainous region is known for its stone villages and arched bridges. The Vikos Gorge is one of the deepest in the world, and the hiking trails here are both scenic and rewarding.

Unmissable summer experiences in Greece

Summer in Greece isn’t just about beach days. There’s a wide range of other activities available, including adrenaline-pumping outdoor adventures, lively local festivals, and a renowned food and wine scene.

Top outdoor adventures from country to coast: hiking, sailing, diving and more

Greece is one of the best European destinations for outdoor lovers. Hiking options are endless, with trails that wind through the mainland and the islands. You can follow clifftop paths through Crete’s Samaria Gorge or explore the scenic routes in Mount Pelion. Even smaller islands like Andros and Paros have trails that connect small villages.

If you’d rather be on the water, charter a sailboat in Lefkada or join a catamaran cruise in Syros. Many local tour operators now offer eco-friendly options, including electric motors and low-emission routes.

For those looking for an underwater adventure, Greece is also an excellent destination for snorkeling and diving. Kalymnos and Alonissos are popular spots, known for their clear waters, underwater caves, and ancient shipwrecks.

Top cultural festivals and traditional celebrations

Summer in Greece is packed with fun festivals and local celebrations. Namely, the Athens Epidaurus Festival is a must if you’re near the capital, with live performances held in historic venues like the Odeon of Herodes Atticus.

In September, Thessaloniki’s Reworks Festival draws crowds with its mix of electronic music, visual art, and urban installations. For major concerts, big-name artists headline Release Athens and Rockwave Festival, attracting music fans from across the globe.

In smaller towns, you can join a panigiri. These village festivals feature traditional music, home-cooked food, and dancing that often lasts until sunrise. Visitors are welcome, and it’s one of the best ways to experience authentic Greek culture.

Greek cuisine, seaside dining and gastronomic experiences

Foodies flock to Greece year-round, but summer is particularly tasty. During this time, you’re spoiled for choice with local markets filled with fresh, seasonal ingredients and restaurants serving boat-to-table cuisines.

Along the coast, menus often feature local favorites like grilled fish, fried zucchini, and stuffed tomatoes. Locals pair these specialties with crisp white wine or a chilled glass of ouzo.

If you want to dive into the local food culture, there are plenty of options. You can visit local markets and browse stalls filled with regional treats as well as olives, honey, and cheeses. You can also take a cooking class to prepare traditional dishes yourself.

If you’re a vino lover, head to the highlands of Crete or the vineyards of Naoussa for tastings and a glimpse into Greece’s winemaking scene.
