Fethiye (Oludeniz) weather in October

October in Kas is still shorts and t-shirt weather by day and a jacket after sunset, with a greater chance of rain than high summer - though the forum's line is that bad weather here does not last long. The sea is the reason to come this late: it stays good for swimming into December and by October is warmer than the pools, which is also why regulars name Kas as a place to learn to dive at the end of the month. The end-of-season feel is more relaxed rather than shut down, because Kas is a working town with visitors year-round and the shops and restaurants stay open. The record: 28C days that feel like 29C, 20.6C nights, 5.1 precipitation days carrying 33.2mm, 10 hours of sun and a 26.6C sea.

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.
