Weather in Kithnos in August
In Kithnos, August brings high-summer weather that is hot and almost completely dry. Average highs reach 31°C / 88°F, with lows of around 23°C / 73°F. Even after dark it stays warm, so a room with air-conditioning makes a difference. Sea temperatures average around 25°C / 77°F, warm enough for long swims. Rain is almost unheard of. Kythnos is a low, quiet island in the western Cyclades, within easy reach of Athens. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. You get about 13½ hours of daylight a day, 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. Plan sightseeing for the early morning or evening, and keep the midday hours for the beach or a shaded taverna.
Swimming in Kithnos in August
Swimming is excellent in Kithnos in August, with the sea averaging around 25°C / 76°F. This is when the sea is at its warmest all year. Try Kolona for clear water. On windy days, choose a beach sheltered from the north, where the water stays calmer. Many coves are rocky or pebbly, so water shoes are useful. Arrive early to get space on the busiest beaches.

Frequently Asked Questions
What time does the sun set in Kithnos in August?
Sunset in Kithnos is at around 8:30 pm at the start of August, around 8:15 pm in mid-August and around 7:55 pm by the end of the month, in Greek local time. The long evenings leave plenty of daylight after the heat of the day.
Is it windy in Kithnos 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 Kolona beach in August?
Yes, but it's at its busiest in August. Arrive early to find space and parking, and bring shade and water. The sandbar links Kythnos to the islet of Agios Loukas.
Do I need a car on Kithnos in August?
It's the best way to explore. Kithnos is spread out, and buses mainly link the port with the busiest beaches and villages, so a hire car lets you reach quieter corners. In August, book early, as rental cars can sell out.
Is August or September better for visiting Kithnos?
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.
