Traveller notes on Milos in September
Notes from nearby Santorini (99 km away)
Milos doesn't have its own notes for September yet — these are about Santorini, close enough to share the season.
Regulars on the Santorini forum split September in two: the first half still runs on August's crowds and prices, and the back half — after most of Europe has gone home — is where the island actually loosens up, with a warm sea and a lot less queueing for the Oia sunset.
Other months in Milos
Milos's forum puts July daytime highs around 28°C, warmer than June, with the meltemi wind a near-constant feature — regularly 13 knots with gusts to 25. Regulars note the wind varies sharply by which side of the island you're on, with south-facing Adamas consistently calmer than northeast-facing Pollonia, and that the island stays busy but manageable through the month.
