Weather in Skiathos in August
In Skiathos, August brings high-summer weather that is hot and almost completely dry. Daytime highs average around 31°C / 88°F, and nights drop to about 19°C / 67°F. Expect just 1 rainy day in a typical August. Sea temperatures average around 26°C / 79°F, properly warm for swimming. Skiathos is covered in pine forest, which keeps it green and gives shade even in the heat of summer. 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 Skiathos in August

Is August a Good Time to Visit Skiathos?
August is a great time to visit Skiathos if you want long beach days, a warm sea and the island at its liveliest. Expect highs of around 31°C / 88°F, lows near 19°C / 67°F and rain on around 1 day.

Frequently Asked Questions
What time does the sun set in Skiathos in August?
Sunset in Skiathos is at around 8:40 pm at the start of August, around 8:25 pm in mid-August and around 8:00 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 Skiathos 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 Koukounaries 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 backed by pine forest and a small lagoon.
Do I need a car on Skiathos in August?
Not necessarily. Buses link Skiathos Town 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 Skiathos?
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.
