Mykonos weather is defined by hot, dry summers and mild, wet winters. The live forecast above shows current conditions, which you can use to plan your trip. The best time for a holiday is June to September, when you’ll get reliable sunshine and warm sea temperatures.
What is the best time to visit Mykonos?
For a classic Greek island beach holiday, aim for June through September. July and August are peak season: temperatures sit around 28–30°C, but the meltemi wind keeps things bearable. May and October are quieter shoulder months, with cooler evenings and lower accommodation prices. Winter (November–March) is too cold and blustery for swimming, but fine for sightseeing if you pack layers.
What should I pack for Mykonos?
In summer, light cotton clothing, a hat, sunscreen and a windproof jacket are essential—the meltemi can whip up suddenly. For spring and autumn, bring a jumper or fleece for evenings. Winters require a warm coat and rain gear. Check the weather in mykonos 10 days before you pack, as conditions can shift quickly outside the main season.
