*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Gediz River (Gediz Nehri) running through Kütahya shows marked seasonal variation in water temperature because of continental climate and variable flow. In spring, snowmelt and higher discharge typically keep the river cold, often around 4–12 °C (39–54 °F). Summer brings the warmest conditions in calmer reaches, with temperatures commonly between 18–25 °C (64–77 °F) though shallow, slow pools can be slightly warmer on hot days. Autumn cooling usually produces intermediate values of about 10–18 °C (50–64 °F). In winter the river can approach near‑freezing in places, with typical water temperatures around 0–6 °C (32–43 °F), especially during cold spells.
Swimming in the Gediz near Kütahya is situational rather than universally encouraged. In warmer months some local stretches with gentle current and acceptable clarity are used for bathing, but safety depends on flow rate, hidden currents, and access points. Water quality also varies along the river; downstream sections have experienced agricultural and industrial impacts, so municipal advisories or posted restrictions should be checked. For health and safety, swimming is best in monitored, calmer spots during summer when temperatures are highest, and should be avoided during high flow or in areas where pollution or strong currents are evident.
