Athens Weather Guide

With long, hot summers and late, mild winters with occasional rain, Athens enjoys 300 days of sunshine a year. Its location in a bowl bound by 3 mountains causes the city’s notorious smoggy haze. Spring and autumn are considered the best seasons to visit the city.

Season and Clothing

Summer: June to September

With a hot, dry summer season, heatwaves and the occasional thunderstorm are a given, especially in the hottest months of July and August when temps have been known to climb above 40 degrees Celsius. If you’re sightseeing in summer, head out before 9am or after 5pm to avoid the heat. Summer is also festival season so don’t miss the 3-day Rockwave Festival held in June at Malakasa, 40 kilometres north of Athens.

Average temperatures: 17 – 34 degrees Celsius.

Appropriate clothing: Swimwear, dresses, shorts, t-shirts and sandals.

Don’t forget: Sunnies, a hat and sunscreen.

Autumn: October to November

With less crowds, ample sunshine and fresh air, the shortish autumn is a great time to explore and climb the 7 historic hills around the city to admire the view. Athens is also the ideal base for a day trip to the islands of the Argosaronic Gulf (Aegina, Hydra and Poros are some of the most popular), Ancient Olympia, Ancient Corinth or the wine country - just 1 hour out of town. Don’t miss the Athenian beachside suburbs as well!

Average temperatures: 10 – 23 degrees Celsius.

Appropriate clothing: Clothes for layering, lightweight shirts, shorts, pants and t-shirts.

Don’t forget: A lightweight jacket.

Winter: December to February

While Athens’ winters are mostly mild and wet, the occasional snowfall has been known to occur in the northern suburbs. December is the wettest month and January the coldest, but still with a bearable daily average of 9 degrees Celsius. As winter is low season in Athens, expect fewer crowds around the main attractions. If it’s rainy, head indoors to check out the museums, ancient landmarks and modern art galleries.

Average temperatures: 5 – 14 degrees Celsius.

Appropriate clothing: Jeans, jumpers, long-sleeve tops, boots and scarves.

Don’t forget: A lightweight, waterproof jacket.

Spring: March to May

With bright, blue skies and crisp air, the springtime months are a great time to get out and about and enjoy the pleasant weather and lesser crowds in Athens. Now is the perfect opportunity to check out the ancient sites and wander around the atmospheric and historic inner-city areas like Plaka and Monastiraki. The popular, 3-day emerging Athens Video Art Festival is usually held around April or May in the Technopolis in Gazi.

Average temperatures: 7 – 26 degrees Celsius

Appropriate clothing: Jeans, shorts, dresses, t-shirts, lightweight shirts and a hat.

Don’t forget: Ballet flats and walking shoes.
