Traveller notes on Skiathos in January
Other months in Skiathos
Skiathos's forum calls July hot and mostly dry, daily highs in the high 20s°C easing only into the mid-20s after dark, with any rain arriving in short, sporadic bursts rather than washing out a day. Regulars flag the UV as genuinely strong — sun protection isn't optional — and credit the sea breeze with making al fresco dinners and beach afternoons bearable during what's both the hottest and busiest month.
