Traveller notes on Naxos in September
Notes from nearby Santorini (78 km away)
Naxos 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 Naxos
Naxos's forum calls August hot, busy, and windy — the meltemi peaks this month, strongest in the afternoon and typically easing at night. Regulars point to west-coast beaches like St. George, Agios Prokopios and Agia Anna as well sheltered from the wind, and note crowds are the bigger complaint than the meltemi itself, with early September suggested as a calmer, still-warm alternative.
