Climate

Marmaris has a Mediterranean climate characterised by a hot and humid summer and cool, rainy winter. Showers and rain are very unlikely between May and October.

Summers are hot and humid, and temperatures can reach over 40°C sometimes during heatwaves in July and August. October is still warm and bright, though with spells of rain, and many tourists prefer to visit in the early autumn, especially in September, because the temperatures are not as hot.

Winters are mild and wet. Winter is the rainy season, with major precipitation falling after November. The annual rainfall can reach to 1,232.7 milimetres (48.531 in); the rainfall is concentrated during scattered days in winter falling in heavy cloudbursts which cause flash floods sometimes in flood prone areas.
