Weather in Koufonisia in August
August is the height of summer in Koufonisia: hot and almost completely dry. Average highs reach 28°C / 82°F, with lows of around 23°C / 74°F. Nights stay warm, so air-conditioning helps. In the water, expect around 24°C / 75°F, properly warm for swimming. Rain is almost unheard of. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. Koufonisia are small, low islands southeast of Naxos, with little shade but some of the clearest water in the Cyclades. Daylight lasts about 13½ hours, leaving long, light evenings. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. Evenings are the best time to be out, when the heat fades and the light softens. Plan sightseeing for the early morning or evening, and keep the midday hours for the beach or a shaded taverna.

In early August, the sun sets in Koufonisia at around 8:25 pm. By mid-month it's around 8:10 pm, and by the end of August around 7:50 pm. All times are Greek local time. The long evenings leave plenty of daylight after the heat of the day.
Is it windy in Koufonisia 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.
Can I visit Pori beach in August?
Yes, but it's at its busiest in August. Arrive early to find space and parking, and bring shade and water. It's reached by a coastal path from Chora or, in summer, by small boat.
Do I need a car on Koufonisia in August?
No. Koufonisia 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 Koufonisia?
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.
