Meteo Fethiye (Oludeniz) in giugno

June in Kas is warm on land and colder in the water than the Turkish Mediterranean leads you to expect, and the reason is geology rather than season: the bay is deep and fed by cold springs, with snowmelt still in them into early May. Regulars hoping for 24 or 25C by mid-June get told the sea will not be what it is in September - our row says 24.1C against a 31.1C day reading as 35C. Their fix is local. The south side of the Cukurbag peninsula has warm water, and Limanagzi, a short boat ride across, is warm too, because neither is in the springs' path. Patara and Kaputas are the beautiful ones and the cold ones. The record: 23C nights, 3.8 precipitation days carrying 14.6mm and 13.6 hours of sun.

Fethiye's forum describes March as genuinely warm in direct sun but noticeably cold in the shade, since the mountains behind town are still snow-capped this time of year - one poster specifically flagged that contrast as catching visitors off guard. It's considered an excellent month for exploring the Lycian ruins under clear blue skies without summer heat or crowds, but the sea itself is still too cold for swimming and pools aren't heated yet. An odd rainstorm can roll through, so pack layers rather than committing to shorts and a t-shirt all day.

Forum posters describe September as lovely and very popular - not as scorching as July/August but still warm, with sea and pools fully warmed up from the summer and ideal for swimming. By late September, posters report daytime highs still reaching the mid-30sC in some years, bearable rather than oppressive, while nights cool down enough that evening layers become worth packing. Brief rain is possible but posters say it typically passes quickly with conditions returning to hot and sunny shortly after. Overall, forum consensus consistently ranks September among the best months to visit Fethiye specifically for the combination of warm beach weather and thinning summer crowds.
