Is the sea warm enough for swimming in Kaş, Turkey, in late July and late September?

In late September, Kaş was reported to have daytime temperatures around 27°C and sea water at roughly the same temperature. Swimming was comfortable, but the peak summer heat was gone and a shirt was useful in the evening.

For a late-September trip, expect strong sun even without extreme heat: it was possible to get sunburned after only a few hours outside. Local observation also suggested cloud build-up and a chance of rain after 1 pm.

Cool sea water in late July may not be limited to Kaş itself: nearby Kalkan also felt very cold during the same period. If water warmth is important, check recent readings for the specific bay before booking.

In late July, the sea in Kaş may feel cool if you expect classic warm Mediterranean water: a reading of about 22°C was reported. Despite hot weather on land, it was described as feeling icy.
