Marmaris has a hot-summer Mediterranean climate with long, dry summers and mild, wet winters. The town sits in a sheltered bay on Turkey’s southwestern coast where the Aegean meets the Mediterranean, giving it a slightly more moderate climate than inland areas. July and August are the hottest months, with daytime highs around 34°C (93°F), while the sea stays warm enough for swimming from May through October. Winter brings occasional rain but temperatures rarely drop below 7°C (45°F), even in January. This Marmaris travel guide covers everything you need to plan your trip.
