Weather in Kalymnos in August
August is the height of summer in Kalymnos: hot and almost completely dry. Daytime highs average around 33°C / 92°F, and nights drop to about 23°C / 74°F. Even after dark it stays warm, so a room with air-conditioning makes a difference. Rain is almost unheard of. In the water, expect around 24°C / 75°F, properly warm for swimming. Kalymnos is a rugged, rocky island, and its limestone cliffs are famous among climbers from all over the world. The meltemi, the northerly wind of the Aegean, blows on many days and takes the edge off the heat, though it can also whip up dust and rough seas. Days bring around 13½ hours of daylight, 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.
Swimming in Kalymnos in August
Expect the sea around Kalymnos to be about 24°C / 76°F in August, comfortable for long swims. Of the best swimming months, July, August and September, this is the warmest. Good spots include Masouri. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Beaches are at their busiest now, so go early or late in the day. No wetsuit needed.
Crowds & Prices in Kalymnos in August
Expect Kalymnos to be at its busiest in August. Prices for rooms, car hire and ferries are at their yearly high. The days around 15 August, a major Greek holiday, are the busiest of all, with ferries and rooms fully booked. Staying slightly outside the main town usually means better value and more space. Book accommodation and ferries months ahead.
What's Open in Kalymnos in August
Ferries to Kalymnos from Piraeus and Kos run at full summer frequency in August, but they sell out, so book ahead. The island also has an airport with flights from Athens.

Festivals & Holidays in Kalymnos in August
15 August, the Dormition of the Virgin Mary, is the biggest summer holiday, with church services and village festivals everywhere. Many Greeks return to their home villages in August, and panigyria, village feasts with live music and dancing, run late into the night. Locals in Kalymnos mark these dates in the traditional way, and visitors are welcome to join in. Look out for posters announcing local feasts and concerts, often only a few days ahead.
Is August a Good Time to Visit Kalymnos?
Yes, August is worth it for sun, swimming and a lively summer buzz in Kalymnos. Expect highs of around 33°C / 92°F, lows near 23°C / 74°F and almost no rain.

Frequently Asked Questions
What time does the sun set in Kalymnos in August?
Sunset in Kalymnos is at around 8:20 pm at the start of August, around 8:05 pm in mid-August and around 7:45 pm by the end of the month, in Greek local time. Masouri is a favorite spot, with the sun setting behind Telendos.
Is it windy in Kalymnos 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 rock climbing on Kalymnos?
It's tough. August is hot, so climbers stick to shaded crags in the early morning or evening. Most climbers prefer spring and autumn.
Do I need a car on Kalymnos in August?
Not necessarily. Buses link Pothia with the main beaches and villages in August, and taxis are available, though they're busy. A car, scooter or ATV gives you more freedom to explore quieter corners, so book one early.
Is August or September better for visiting Kalymnos?
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.
