Weather in Athens in August
August is the height of summer in Athens: hot and almost completely dry. Temperatures typically peak at around 33°C / 92°F in the afternoon and fall to about 24°C / 75°F at night. Nights stay warm, so air-conditioning helps. Expect just 1 rainy day in a typical August. The sea averages about 26°C / 79°F, properly warm for swimming. Athens sits in a basin ringed by mountains, which traps heat in summer and keeps the city drier than much of Greece. Heatwaves are common in summer, and sea breezes are the main relief near the coast. Daylight lasts about 13½ hours, leaving long, light evenings. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. The sun is strong from mid-morning onwards, even when a breeze makes it feel cooler. Evenings are the best time to be out, when the heat fades and the light softens. Get out early and late, and save the hottest hours of the afternoon for the water.
Swimming in Athens in August

In Athens, as across Greece, these traditions are very much alive. Look out for posters announcing local feasts and concerts, often only a few days ahead.

Is Athens too hot in August?
It can be. August is hot, dry and sunny, and heatwaves are common. Breezes help near the sea, and evenings are warm enough to eat outdoors, but walking around in the midday sun is tiring. Carry water, wear a hat and save sightseeing for the early morning or evening.

Do I need a car in Athens in August?
No. Athens has a good metro, trams and buses, and the historic center is compact and walkable. A car is more hassle than help in the city, though it's useful for day trips to places like Cape Sounion. In August, the air-conditioned metro is a welcome escape from the heat.
Is August or September better for a trip to Athens?
September, clearly. The heat eases, the city comes back to life after the summer holidays, and it's still warm enough for a beach day. August is hot, and some local businesses close.
