Weather in Mykonos in August
In Mykonos, August brings high-summer weather that is hot and almost completely dry. Daytime highs average around 28°C / 82°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. Sea temperatures average around 24°C / 75°F, properly warm for swimming. Summer weather here is shaped by the meltemi, a dry northerly wind that keeps the heat bearable but can make exposed beaches choppy. Mykonos is small, low and famously windy, which is why its landmark windmills stand on the ridge above town. 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 Mykonos in August
The sea in Mykonos averages around 24°C / 75°F in August, warm enough to stay in for as long as you like. Of the best swimming months, July, August and September, this is the warmest. Psarou, Platis Gialos and Ornos are local favorites. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Arrive early to get space on the busiest beaches. You won't need a wetsuit.
Crowds & Prices in Mykonos in August
August brings peak crowds to Mykonos. Accommodation is at its most expensive, and the best rooms go early. The days around 15 August, a major Greek holiday, are the busiest of all, with ferries and rooms fully booked. On cruise-ship days, the main sights are busiest between late morning and mid-afternoon. The crowds concentrate at Mykonos Town and Little Venice at sunset, so for a calmer experience, head inland to Ano Mera or explore town early in the morning. Book early, as the best-value rooms go first.
What's Open in Mykonos in August
Ferries to Mykonos from Piraeus and Rafina run at full summer frequency in August, but they sell out, so book ahead. The airport has direct flights from across Europe in the season, as well as flights from Athens. Everything is open, from hotels and tavernas to beach bars and boat trips. Museums and sites are open on extended summer hours. Beach clubs and bars are in full swing.
Festivals & Holidays in Mykonos in August
Many Greeks return to their home villages in August, and panigyria, village feasts with live music and dancing, run late into the night. 15 August, the Dormition of the Virgin Mary, is the biggest summer holiday, with church services and village festivals everywhere. Locals in Mykonos mark these dates in the traditional way, and visitors are welcome to join in. Summer evenings are the time for festivals, open-air cinemas and late dinners outdoors.
Is August a Good Time to Visit Mykonos?
Yes, August is worth it for sun, swimming and a lively summer buzz in Mykonos. In numbers: highs of about 28°C / 82°F, lows of 23°C / 74°F and almost no rain in a typical August. The trade-off is crowds and peak prices, so book early and plan around the busiest spots. If you'd rather have the same warm sea with more space, June, September or October would be a better choice.
Frequently Asked Questions
What time does the sun set in Mykonos in August?
Sunset in Mykonos is at around 8:30 pm at the start of August, around 8:15 pm in mid-August and around 7:50 pm by the end of the month, in Greek local time. Little Venice and the windmills above it are the classic places to watch it. Arrive at least half an hour early to find a spot.
Is it windy in Mykonos 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 Delos in August?
Yes. Boat trips to Delos run regularly in August, but they're busy, so book ahead or take the first departure of the day. Trips can still be cancelled on very windy days. Boats leave from Mykonos Old Port, and the site itself has almost no shade.
Do I need a car on Mykonos in August?
Not necessarily. Buses link Mykonos 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 Mykonos?
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.
