Meteo Fethiye (Oludeniz) in agosto

Regulars quote an August average high of 30.7C and a discomfort that comes from the nights rather than the days, with minimums of 25 to 26C - our row reads 30.6C and 25.1C, which is as close as these things get. July and August are the meltemi's peak: it blows from between north-east and north-west, hardest in the afternoon, often dropping at night, and it is what tempers the heat. That makes the island two places. The west is windier with rougher beaches and runs mid to high thirties; the east is calmer, sandier and sheltered, and several degrees hotter for exactly that reason. The record: 0.8mm of rain, 12.4 hours of sun, a 27.7C sea and AQI 81.

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.
