Mykonos in April

May through October marks Mykonos season, but timing makes all the difference. May and early June offer the sweet spot: warm weather, fewer crowds, and hotels that haven't reached peak pricing. The sea might still be chilly for swimming, but beach clubs start opening and the party scene kicks into gear. July and August bring peak chaos. Temperatures soar into the mid-30s, beaches pack with bodies, and hotel prices reach astronomical levels. But this is also when Mykonos truly comes alive – every club operates at full capacity, and the energy becomes infectious. September delivers the best weather with slightly smaller crowds. The sea reaches its warmest temperature, and that harsh summer light softens into something magical. October extends the season for those seeking deals, though many beach clubs start closing. Winter turns Mykonos into a ghost town. Most hotels, restaurants, and attractions shut down from November through March. The few places that stay open cater to locals, offering a completely different experience of the island.
