Meteo Fethiye (Oludeniz) in maggio

Regulars are consistent that weather here has more or less settled by mid-month, temperatures climbing past 30C by the end, with cloud or a little rain now the genuine exception rather than something to plan around. Our row backs that warm, genuinely dry read, 24.2C over 18.1C nights, with rain minimal at 13.4mm across just 3.1 days and humidity at 76 percent. Regulars are specific that the island's southeast side runs slightly warmer and drier than elsewhere, a real factor worth weighing when picking a base. The sea sits at a cool 19.6C, not yet warm enough for most to swim comfortably despite the reliably sunny days on land. The record: 12.5 hours of sun, a 21.8 kph wind and AQI 61.

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.
