When Is the Best Time to Visit Mykonos? Month-by-Month Guide

April is the island waking up. The days warm quickly, averaging around 18°C with the best afternoons in the low twenties, and the hills are still green from the winter rain. In Chora you'll see more people touching up the whitewash than tourists. The sea is about 16°C, so swimming is for the brave, and a lot of places only open in the last few days of the month.

It's a beautiful time for walking, taking photos and seeing Delos without the crowds. It's even better when Greek Easter lands in April, as it does on 16 April 2028. Easter is the biggest holiday of the Greek year, and here it means candlelit processions winding through the lanes on Good Friday and the midnight service on Saturday. Just don't come expecting beach clubs. That Mykonos is still a few weeks away.

May is when the lights come on. In 2026 Nammos opened on 1 May, Cavo Paradiso on the 9th, SantAnna on the 12th and Spilia on the 23rd, and by the last week nearly everything was open. Highs average about 22°C, the warmest days near the end of the month get close to 28°C, and there's around 9.5 hours of sunshine a day. The sea sits around 18.5°C. That's a shock in early May and perfectly pleasant for most people by the end.

This is the value month. You pay shoulder season prices, and by late May you get an island that's almost fully open. One thing to know: May is one of the two big cruise months, so Chora can be crowded around midday even when the beaches are calm. In 2027 Greek Easter falls on 2 May, which brings lots of Greek visitors, a lovely festive mood and a very full weekend.

June is real summer, just before the rush. Highs are around 26 to 27°C, the days last about fourteen and a half hours, and rain is almost unheard of. The sea is about 21.5°C, refreshing more than warm, and fine for a proper swim. Everything is open, and the beach clubs have a good buzz without the August squeeze.

Two things are worth knowing. The meltemi starts showing up in June, usually gentler than in July, and a windy terrace can feel chilly after dark, so bring a light jumper. And June is really two months in one. The first half still feels relaxed, while the last week already feels like July, in crowds and in price. On 30 June the island celebrates the Holy Apostles, traditionally the fishermen's feast.

July is hot, dry and full. Highs average about 28.5°C and the hottest days reach 34°C or so. It's the driest month of the year and it barely rains at all. The sea is a very comfortable 23.5°C. From the middle of the month the island is at capacity, so hotels, ferries and any table you really want should be booked well ahead, often months rather than weeks.

It's also the heart of meltemi season. The wind is what makes the heat bearable, but on a strong day the north coast gets sandblasted. The rule is easy: when the meltemi blows, go south. Psarou, Platis Gialos, Ornos and Paraga are tucked out of the wind, while Ftelia, Panormos and Agios Sostis are left to the kitesurfers. Late July also has two small chapel feasts, Agia Paraskevi on the 26th and Agios Panteleimon at Marathi on the 27th.

August is Mykonos turned all the way up. It's the busiest month, the most expensive and, on average, the windiest. The sea is at its warmest, around 24°C. Hot days reach the low thirties, but the meltemi usually keeps things bearable. If you want the biggest DJs and every terrace packed, this is your month.

It's also when the island feels most Greek. 15 August, the Dormition of the Virgin, is a national holiday, and Greek families travel in huge numbers around it, so ferries and rooms are at their tightest that week. The real celebration happens at the Panagia Tourliani monastery in Ano Mera: a free village festival on the evening of the 14th, then the liturgy and procession on the 15th. The monastery has a second, quieter feast on 23 August. The second half of the month usually brings XLSIOR, one of the biggest LGBTQ+ festivals in Europe, and rooms go months in advance.

If we could only recommend one month, it would be September. Highs are around 26°C and the sea is still about 23.5°C, warmer than in June. Once European schools go back, you can feel the island breathe out. The beach clubs stay open all month, and the closing parties at the end have a mood you won't find at any other time.

A few things to bear in mind. The meltemi can still blow hard, especially early on, and a handful of rainy days start to come back. Like May, September is a big cruise month, so Chora is at its busiest from late morning to late afternoon. The days are shorter too, about twelve and a half hours. For something truly local, the grape harvest festival at the Agricultural Museum next to Boni's windmill usually happens in the middle of the month, with grape treading, folk music and local wine.

October is like May in reverse, with one big advantage: the sea. The first half of the month often still feels like summer. Highs are around 22°C, the warmest days reach the middle twenties, and the water is about 21.5°C, noticeably warmer than in May. Prices drop sharply and the island goes quiet.

The downside is that the season closes around you. Beach clubs and many boutique hotels shut between late September and the middle of October, ferries run less often, and the rain comes back, with around five wet days on average. The first two weeks are a real bargain. The last two are a gamble: lovely in a good year, grey in a bad one.

Winter Mykonos is a different island: small, local and working. Highs drop from about 18°C in November to around 13°C in January and February. Most of the year's rain falls between November and January, and the sea, somewhere between 15.5 and 19°C, is too cold for most of us. Most hotels, all the beach clubs and plenty of restaurants close, and the buses run less often.

Getting here takes more planning. Direct international flights stop for the winter, so nearly everyone connects through Athens. On top of that, runway works will close Mykonos airport every Thursday from 19 November 2026 to 18 March 2027, apart from a few dates around Christmas and Epiphany. Ferries from Piraeus and Rafina run all year, but there are fewer of them and bad weather cancels more. Delos is only open on a very limited basis. What you get in return is an empty Little Venice, the lowest prices of the year, and the island as the people who live here know it.
