Weather in Pserimos in September
Expect hot, almost completely dry weather in Pserimos in September, late summer. Average highs reach 29°C / 84°F, with lows of around 20°C / 68°F. Expect just 1 rainy day in a typical September. Sea temperatures average around 24°C / 75°F, warm enough for long swims. Pserimos is a tiny island between Kos and Kalymnos, with a sandy main beach and almost no shade. The summer winds ease, and the light turns soft and golden. You get about 12½ hours of daylight a day. 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. Mornings and evenings get noticeably cooler as the month goes on. The weather can change from one week to the next, so pack for both warm and cool days. Plan sightseeing for the early morning or evening, and keep the midday hours for the beach or a shaded taverna.

Can I take a day trip to Pserimos in September?
Yes. Day-trip boats from Kos Town and Kalymnos run regularly in September, and the main beach gets busy around midday when they arrive. Stay later, or overnight, to enjoy the quiet.
Do I need a car on Pserimos in September?
No. Pserimos is small enough to explore on foot, and the distances between the harbor, village and beaches are short. In September, some beaches may also be served by small boats or a seasonal minibus, and it's worth bringing a hat for the walks.
Is September or October better for visiting Pserimos?
September, if you want swimming and everything open. October is quieter and cheaper, and the sea often stays pleasant early in the month, but the weather becomes more changeable and many seasonal hotels, tavernas and boat trips wind down as the month goes on.
