The best time to visit Kaş, month by month
Updated: 2026-07-30
Kaş has a long season by Mediterranean standards — you can swim from May into November — but the town changes character month to month. The honest sweet spots are June and September.
May and June: the coast waking up
May is warm days, fresh evenings and a sea around 19–21°C — swimmable if you are keen, glorious if you are a walker or diver. June is the first sweet spot: sea in the mid-20s, everything open, light that photographers cross continents for, and crowds still merciful.
July and August: full summer
Peak heat (mid-30s), peak sea (up to about 28°C), peak everything else. Boats are fullest and paragliding slots go fastest — book activities a couple of days ahead. It is hot for canyon-and-ruin days, perfect for anything that involves being wet every twenty minutes.
September and October: the second summer
September is the other sweet spot, and arguably the best month of all: the sea holds near 26–27°C, evenings soften, and the July crowds are a memory. October keeps a genuinely warm sea (around 23–24°C) with quiet bays and shoulder-season prices; some boats and flights thin out late in the month.
Winter: the town to itself
From November to April Kaş belongs to residents, climbers and walkers — many tour operations pause, but the Lycian Way is at its best and divers with decent suits dive all winter. Do not come in January for a beach holiday; do come for empty ruins and long lunches.
