Meteo Fethiye (Oludeniz) in gennaio

Kas-forum threads on January weather describe real year-to-year variation - some winters mild enough for a comfortable evening in a tea garden, others properly cold, with late January and February consistently singled out as the coldest, rainiest stretch of the whole year on this coast. When rain does arrive, regulars describe it as heavy rather than a drizzle, but rarely prolonged across multiple days in a row - a hard downpour that clears rather than settling in for a week. Evenings run genuinely cold regardless of how mild the day felt, a proper coat needed after dark. The practical complication for a January visit: the tourist season formally closes around October 29th, so many hotels and restaurants are shuttered through winter, narrowing the options considerably compared to summer. The record: 17.2C days feeling like 15C, 10.9C nights, a notably high 179mm across 14.2 days, 4cm of snowfall in the hills, a 19.2C sea and 7.9 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.
