Weather in Agistri in September

September in Agistri means late-summer conditions: hot and mostly dry. Daytime highs average around 29°C / 84°F, and nights drop to about 20°C / 68°F. The sea averages about 25°C / 77°F, warm enough for long swims. Expect just 2 rainy days in a typical September. Agistri's pine forests give welcome shade and keep the island greener than most in the Saronic Gulf. The heat eases, and the sea stays warm long after the summer crowds have gone. You get about 12½ hours of daylight a day. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. The weather can change from one week to the next, so pack for both warm and cool days. Mornings and evenings get noticeably cooler as the month goes on. The light is softer than in summer, which makes it a lovely time for photos and walks. Get out early and late, and save the hottest hours of the afternoon for the water.
