Traveller notes on Mykonos in May
Other months in Mykonos
Mykonos's forum calls July hot, typically 30-32°C by day, but genuinely more bearable than the number suggests thanks to essentially no humidity. Regulars flag the island's famous meltemi wind as the real variable — strong enough at the harbor front to need a jumper for an evening out, but sheltered spots like Platis Gialos stay comfortable.
