Athens Weather

The weather in Athens changes according to the season and presents the elements of the typical Mediterranean climate.

In brief, Athens is a warm city where extreme weather phenomena are rarely presented. The most wearying weather is that of July and August due to frequent heatwaves; that is the time when the beaches get more crowded than ever.
The best months to visit Athens are May, June, and September as the sky is still clear, the days are long and the temperatures are high but do not exhaust you. These are the ideal periods to visit the sights and participate in tours and activities!

Summers in the capital of Greece are very hot and dry, especially during July and August, while winters are usually mild with some wet days.

Taking sun protection measures during the summer is *extremely* crucial. The center of Athens is full of buildings and vegetation is limited, with the building materials exacerbating the heat to the point where Athens is the hottest capital in Europe!
People planning a visit during the summer months should be particularly careful. Walks and visits to places of interest located outdoors should be avoided during the hours when the heat is most intense (approx. 11:00 - 16:00), while personal protection measures (frequent application of sunscreen, wearing a hat and sunglasses and hydration) are essential to avoid sunburn, dehydration and sunstroke!
