Weather in Rethymno in September

September in Rethymno means late-summer conditions: hot and almost completely dry. Expect highs of about 28°C / 82°F and overnight lows near 19°C / 67°F. Sea temperatures average around 25°C / 77°F, warm enough for long swims. Rain is rare, with only 1 wet day in an average September. Rethymno sits on Crete's north coast between Chania and Heraklion, with the Psiloritis range rising to the south. The first autumn showers are usually short and sharp, and the mountains start to cool quickly. Days bring around 12½ hours of daylight. Bring loose, light clothing, a wide-brimmed hat, strong sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. The weather can change from one week to the next, so pack for both warm and cool days. Get out early and late, and save the hottest hours of the afternoon for the water.

Swimming in Rethymno in September

The sea in Rethymno averages around 25°C / 77°F in September, warm enough to stay in for as long as you like. The best swimming runs through July, August and September, and the water is still close to its August peak. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Beaches are lively but less crowded than in high summer. No wetsuit needed.

Crowds & Prices in Rethymno in September

In Rethymno, September strikes a good balance between atmosphere and space. Prices are noticeably lower than in high summer, and there's more choice of rooms.

Weekdays are calmer than weekends at the most popular spots. Booking a few weeks ahead is usually enough.

Festivals & Holidays in Rethymno in September
