Weather in Mykonos in September
In Mykonos, September brings late-summer weather that is warm and almost completely dry. Expect highs of about 26°C / 79°F and overnight lows near 21°C / 70°F. Expect just 1 rainy day in a typical September. The sea averages about 23°C / 73°F, pleasant for a swim. Mykonos is small, low and famously windy, which is why its landmark windmills stand on the ridge above town. The first autumn storms can arrive, usually as short, sharp showers between long spells of sunshine. You get about 12½ hours of daylight a day. Summer clothes are fine by day, with a light layer for the evenings and plenty of sunscreen. When the wind picks up, a light windproof layer is handy for evenings by the water. The weather can change from one week to the next, so pack for both warm and cool days. It's pleasant to be outside from morning to evening, with sun protection at midday.
Swimming in Mykonos in September
Swimming is excellent in Mykonos in September, with the sea averaging around 23°C / 74°F. The best swimming runs through July, August and September, and the water is still close to its August peak. 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. Beaches are lively but less crowded than in high summer. No wetsuit needed.
Crowds & Prices in Mykonos in September
Expect Mykonos at its busiest in September, with the island's most famous spots packed from morning to night. Accommodation is at its most expensive, and the best rooms go early.

The busiest spot is Mykonos Town and Little Venice at sunset; for more space, head inland to Ano Mera or explore town early in the morning. Book accommodation and ferries months ahead.
What's Open in Mykonos in September
Ferries to Mykonos from Piraeus and Rafina run at full summer frequency in September, but they sell out, so book ahead.

Is September a Good Time to Visit Mykonos?
