*** 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.

Location & Local Information
Ulutan Dam’s reservoir in Zonguldak experiences a clear seasonal cycle in water temperature. In winter the surface water typically ranges around 2–6 °C (36–43 °F), rising during spring to roughly 8–15 °C (46–59 °F) as air temperatures warm and inflows increase. Peak summer surface temperatures commonly reach about 18–24 °C (64–75 °F), though shallow bays warm faster while deeper parts remain notably cooler. In autumn the lake cools back to approximately 10–16 °C (50–61 °F). These figures are approximate and vary with annual weather patterns, inflow rates and wind-driven mixing; deeper or shaded areas will often be several degrees colder than surface measurements.
Swimming at Ulutan Barajı is generally discouraged and in many reservoirs effectively prohibited, primarily for reasons of water supply protection and safety. As a managed reservoir the lake may serve irrigation or potable water purposes, leading authorities to restrict recreational contact to prevent contamination. In addition, submerged structures, steep banks and cold, stratified water layers create hazards for swimmers and boaters. Local regulations and signage determine the exact rules, so anyone considering entering the water should check with municipal or water management authorities and heed posted warnings.
