Water Temperature Trends
Turkey's long coastline spans several seas, so coastal water temperatures vary by region and season. Along the warm Mediterranean and Aegean coasts, surface temperatures commonly reach about 22–30 °C (72–86 °F) in summer months, making swimming comfortable from late spring through early autumn. In autumn these seas cool more slowly and often remain around 18–26 °C (64–79 °F) into October, while winter surface temperatures typically fall to roughly 12–18 °C (54–64 °F). The Black Sea is cooler year-round, with summer values often in the 20–24 °C (68–75 °F) range and winter temperatures dropping to around 6–12 °C (43–54 °F). The inland Marmara Sea and sheltered bays sit between these extremes, generally ranging from about 10–25 °C (50–77 °F) through the year.
Swimming Conditions
Freshwater bodies show wider variation because of altitude, depth and seasonal runoff. Lowland lakes and slow rivers can warm to 15–25 °C (59–77 °F) in summer and be suitable for bathing, while high-altitude lakes and mountain rivers remain much colder, often 4–15 °C (39–59 °F) even in summer due to snowmelt. Springtime snowmelt keeps many rivers brisk and unsafe for long swims, with temperatures commonly below 10–14 °C (50–57 °F). Swimming is widely practiced along the Aegean and Mediterranean coasts during the warm months, with many beaches designated for bathing; in rivers and lakes swimming is allowed in many areas but requires local judgment about currents, water quality and temperature, and colder waters may necessitate caution or a wetsuit for comfort and safety.
