Weather in Kasos in August
August is the height of summer in Kasos: hot and almost completely dry. Daytime highs average around 30°C / 87°F, and nights drop to about 25°C / 77°F. Even after dark it stays warm, so a room with air-conditioning makes a difference. You're very unlikely to see any rain. The sea averages about 25°C / 77°F, properly warm for swimming. Kasos is a small, remote island between Karpathos and Crete, fully exposed to the open sea. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. Daylight lasts about 13½ hours, leaving long, light evenings. 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. Get out early and late, and save the hottest hours of the afternoon for the water.

What time does the sun set in Kasos in August?
Through August, sunset in Kasos moves from around 8:15 pm to around 7:45 pm in Greek local time, as the evenings get shorter. In mid-August, expect it at around 8:05 pm. The long evenings leave plenty of daylight after the heat of the day.
Is it windy in Kasos in August?
Often, yes. August is the height of the meltemi, a strong, dry northerly wind that blows across the Aegean on many summer days, sometimes for several days in a row. It keeps the heat bearable, but it can make exposed beaches rough and delay fast ferries and small boats. South-facing beaches are usually more sheltered.
Is August a good time for walking on Kasos?
Only early in the morning or late in the day. August is hot, most paths have little shade and the midday sun is fierce. Start at dawn, carry plenty of water and wear a hat. Paths lead from the small harbor villages into the quiet hills.
Do I need a car on Kasos in August?
No. Kasos is small enough to explore on foot, and the distances between the harbor, village and beaches are short. In August, some beaches may also be served by small boats or a seasonal minibus, and it's worth bringing a hat for the walks.
Is August or September better for visiting Kasos?
September, for most travelers. The sea is still warm, the crowds thin out after the first week or two and prices drop, while most businesses stay open. August is the choice only if you want the island at its busiest and liveliest.
