Traveller notes on Fethiye in December

Notes from nearby Kaş (67 km away)

Fethiye doesn't have its own notes for December yet — these are about Kaş, close enough to share the season.

Kas-forum threads on December weather describe a sea still warm enough for a swim and days that regulars call usually mild, with January and February singled out as the genuinely wetter months by comparison - meaning December, while not dry, sits toward the better end of the winter stretch. One visitor recalls sitting comfortably in a tea garden on Christmas Day itself, though evenings turn properly cold once the sun is down, a real jacket needed after dark even on a mild day. The practical catch for December specifically: the town's tourist season formally closes on October 29th, so many hotels and restaurants are shuttered by winter, leaving a smaller, more local set of options open. Posters do note the occasional rough patch - one account described a genuinely stormy late-December stretch with boats lifted from the harbor - but call it an exception rather than the rule. The record: 19C days, 13C nights, 158mm across 13.4 days, 73 percent humidity, a 21.1C sea and 7.7 hours of sun.

Other months in Fethiye

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.
