High summer: July and August
These are the hottest, busiest and most expensive months, with sea temperatures around 27°C and guaranteed sunshine. It's ideal if you want lively evenings and the warmest swimming, but book boat trips and accommodation ahead, and start beach days early.
The sweet spot: June and September
Many regulars say June and September are the best time to visit Kaş. The sea is warm, the days are long and sunny, but the crowds and prices ease off. Boat trips run reliably and the bays feel calmer — a great balance for families and couples alike.
Spring and autumn shoulders: April, May & October
These months are warm and green, perfect for diving, walking sections of the Lycian Way and sightseeing without the heat. The sea is swimmable for many from late May and into October. Some boat tours run on a reduced schedule, so it's worth checking dates in advance.
Month by month: a quick reference
April brings 18 ‑ 22°C air and 17 ‑ 18°C sea — fine for hiking, brisk for swimming. May warms to 23 ‑ 26°C with the sea climbing past 20°C; the first wave of boat tours opens up. June and July deliver 28 ‑ 32°C days and 24 ‑ 27°C water. August is the hottest at 32 ‑ 35°C with sea around 28°C; pace yourself in the middle of the day. September stays summery (28 ‑ 30°C, sea 26 ‑ 27°C) with thinner crowds. October eases to 22 ‑ 27°C with the sea around 23°C, perfect for late season swimmers. From November to March, expect 12 ‑ 18°C and occasional rain.
Best time for boat trips and Kekova
The boat trip season runs reliably from late April through the end of October. Conditions are best from June to mid September, with calm seas, light morning breezes and the warmest water. Early July to mid August is peak crowd, so consider an early start (08:00 sunrise charter) or a private boat for breathing room. For Kekova specifically, the morning light over the sunken city is at its best between 10:00 and 13:00 — most day tours arrive in this window. Avoid the windiest March and November days unless you book a private charter that can pivot to a sheltered route.
What to avoid: school holidays, religious holidays and meltemi
Three windows pack Kaş tighter than usual. Turkish school holidays (mid June to mid September) bring domestic visitors at weekends. The two religious holidays, Ramazan Bayramı (Eid al Fitr) and Kurban Bayramı (Eid al Adha), shift each year but always trigger a four to nine day spike — accommodation books out weeks ahead and roads from Antalya are slow. The meltemi, a north wind that blows hardest in late July and August, can ruffle the sea by mid afternoon; morning boat tours dodge it. None of these are reasons not to come, just to book earlier.
