The best time to visit Greece is spring or fall, either side of the hot, dry summer. Of course, summer is also a great time to go to Greece for the beaches, the swimming, and long, lazy lunches in waterfront tavernas.
Greece enjoys a typical Mediterranean climate of mild, wet winters and long, usually rain-free summers. Inland, snow often falls on the mountains in winter.
The tourist season in Greece’s islands and along the coasts extends from April, when days are still cool and manageable, to the end of October, when you’ll enjoy clear days, but cooler nights.
Athens, however, is making a name for itself as a year-round destination among those who come for the superb museums and antiquities, with the shoulder season extending well into November.
Visiting Greece by Season
Summer
Athens
Summers in Greece, on the mainland and in the islands, are hot and dry; in fact, Athens is regarded as the hottest capital in Europe. Fortunately, the city is blessed with a beautiful riviera, lined with hotels and beach clubs, where locals go to escape the heat.
June is a pleasantly warm month, with Athens seeing average daily highs of 77.7°F (25.4°C). July and August are when sun-seekers from all over Europe flock to the Aegean, and sightseeing has to be managed to avoid the intense heat of midday. Expect average highs of 83.3°F (28.5°C) in Athens in August and 78.6°F (25.9°C) in Santorini.
This is a time to slow down to the locals’ pace, snooze during the heat of the day, and enjoy the relative cool of the early morning and early evening.
Summer in Greece can be windy, as the Meltemi, a wind from the north and northeast, begins to blow. The wind tends to pick up in the afternoons, calming down by early evening. The breeze is certainly cooling, but the sea can be choppy for watersports like windsurfing and kayaking.

Summer Vibes
Summer in Greece is both energetic and relaxed. On the one hand, you can experience golden beaches and open-air seaside dining. Island beach clubs buzz with music, and travelers enjoy late-night dinners under starry skies. But depending on where you are, the pace of life may slow to a crawl while many locals and visitors alike nap or enjoy downtime during the mid-afternoon heat.
Summer Weather
Summer brings hot, dry conditions with daily temperatures frequently climbing into the high 80s and 90s Fahrenheit. But while the air is hot, sea temperatures are welcoming. They reach their warmest levels of the year, providing ideal conditions for swimming and water activities.
Fall
Elia Beach, Mykonos
Fall is arguably the best time to go to Greece, with the long summer extending through September into early October. Temperatures have dropped in Athens to a more manageable 67.8°F (19.9°C) by October, but the days are usually sunny and clear, and the sea is still deliciously warm for swimming.
By November, the weather has cooled down considerably, with Athens seeing average highs of 59.6°F (15.3°C).
Fall Vibes
Fall offers a laid-back, golden charm as peak summer crowds diminish and a more relaxed atmosphere takes hold across the islands. Waterfront villages retain their inviting warmth, allowing guests to savor long seaside meals without the high-season bustle. The mood is tranquil and sophisticated, perfect for peaceful coastal walks and historical exploration.
Fall Weather
Early autumn maintains the summer warmth with temperatures hovering in the high 70s and low 80s Fahrenheit, while the sea remains comfortably warm for swimming. As November approaches, cooler breezes and occasional rain showers arrive, bringing crisp autumn air to the mainland.
Winter
Greece is a seasonal destination, apart from Athens and, to an extent, Thessaloniki, which have year-round appeal. From December to February, the islands are extremely quiet and many of the locals take time off after the busy summer.
The weather is cool, and rain is frequent, at least up to March. In the Greek cities, however, there’s still plenty going on.
Winter Vibes
Winter showcases an authentic, peaceful side of Greece that fewer people get to see. Island life turns quiet and reflective, while historic mainland cities like Athens buzz with local cafe culture and museum-goers. It provides a peaceful setting to experience genuine local traditions at a more relaxed pace.
Winter Weather
Winter temperatures are cool and variable, typically averaging in the 50s Fahrenheit across southern islands and mainland coastal areas. Rainfall is at its annual high, and higher-elevation inland regions can even see dustings of snow.
Spring
Spring is a beautiful time to visit Greece. The sea will still be chilly after the winter, but the air is clear. Restaurants and bars are opening up. In Crete, the valleys are lush and green, strewn with wildflowers. Expect average highs of 66.1°F (19°C) in the southern Aegean by May.
Note that Easter for the Greek Orthodox faith follows the Julian calendar and falls a few weeks after the Catholic and Protestant Easter, which is determined by the Gregorian calendar.
Greek Easter usually falls in April or May and is considered the most important holiday of the year, with services and celebrations taking place throughout Holy Week. This can be a wonderful time to visit to learn about Greek traditions.
Spring Vibes
Spring brings a revitalizing atmosphere to the Greek islands and mainland, spurring wildflowers to bloom along coastal trails. Local tavernas open their doors for the season, offering a laid-back, welcoming atmosphere. The mood is upbeat yet unhurried, making it a wonderful time to engage with local culture.
Spring Weather
Temperatures during spring are pleasantly mild, ranging from the low 60s to mid-70s Fahrenheit across most regions. Rainfall drops significantly by April and May, offering abundant sunshine and comfortable conditions for sightseeing.
When Is Rainy Season?
November to March is the rainiest time in Greece. Up to 2.4 inches (60 mm) falls in December, the wettest month, which could see 11 rainy days. On higher ground, in the mountains to the north and even in Crete, precipitation may fall as snow.
Otherwise, you’ll see little rain in summer, although June can be prone to thunderstorms.
When Is High Season?
Mykonos Town
High season in Greece is the summer, from late June to early September. July and August are the busiest months for beach lovers.
Islands like Mykonos and Santorini can be busier than usual during summer. In Athens, you’ll need to time your visit to the Acropolis and other sites to avoid the heat. Evenings are especially lively, with bars and restaurants doing a bustling trade late into the night.
When Is Shoulder Season?
Greece in April is when the shoulder season starts, continuing until early May, and then September and October, stretching into early November as the Mediterranean season continues to extend.
Both spring and fall are wonderful times to visit, with fewer crowds, spectacular hiking, and temperatures warm enough to dine outside.

When Is Low Season?
Kalafatis Beach, Mykonos
Low season in Greece is January and February, when the weather is at its coolest and wettest. The islands are quiet now, with many establishments closed as the owners take a much-needed vacation.
Best Time To Visit Greece for Beaches and Swimming
If your ideal vacation involves brilliantly blue Aegean waters, then late June through September is the best season to visit Greece. Sea temperatures peak during July and August, offering swimmers warm, inviting conditions along famous stretches of sand. Early September also delivers exceptional beach conditions with warm sea temperatures, sunny skies, and slightly smaller shore crowds.
Best Time To Visit Greece To Avoid the Crowds
For travelers seeking quieter cobblestone lanes and archaeological sites, the shoulder months of April, May, October, and November represent the best time of year to visit Greece. During these windows, major destinations like Santorini and the Acropolis offer less busy sightseeing opportunities. These periods also allow for easier restaurant reservations and more intimate interactions with local island communities.
Best Time To Visit Greece by Region
The Cyclades (Santorini, Mykonos)
The Cyclades are exceptional destinations from May through October, when ferry schedules run frequently, and island venues are fully operational. July and August deliver bustling nightlife and high energy, while May, June, September, and October provide pleasant weather and a more relaxed island atmosphere.
The Ionian Islands (Corfu, Zakynthos)
Situated off Greece’s western coast, the Ionian Islands feature lush greenery and temperate sea breezes. Late May, June, and September offer ideal conditions for taking boat to Navagio Beach or exploring historic Venetian towns without peak summer heat.
Crete
As Greece’s southernmost island, Crete enjoys one of the longest warm seasons in Europe, making it appealing year-round, but especially from April through November. Spring brings blooming mountain gorges perfect for hiking, while late autumn keeps the southern coast warm enough for swimming long after northern ports have cooled.
Athens and the Mainland
Athens and historic mainland sites like Delphi and Olympia are finest during the shoulder seasons of spring (April to May) and fall (September to October). Cooler temperatures make walking among ancient ruins comfortable, while urban cafes and historic neighborhoods remain lively and accessible. For those more interested in the culture and history of Greece than idyllic beaches, the winter months can provide a great opportunity to capitalize on low-season availability.
Choosing a Time To Visit Greece
When planning a trip to Greece, try to align your itinerary with your travel priorities, weather preferences, and activity goals. If you prioritize hot days, vibrant beach clubs, and swimming, July or August is the best month to visit Greece. Alternatively, choosing spring or autumn provides milder temperatures for exploring historical landmarks, quiet coastal villages, and scenic hiking trails at your own pace.
