*** 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
Düzce’s inland water bodies show distinct seasonal temperature patterns driven by the region’s temperate climate and varied topography. Shallow lakes and wetlands such as Efteni typically range from about 2–8 °C (36–46 °F) in winter to 18–26 °C (64–79 °F) in summer, with spring and autumn transition bands around 8–15 °C (46–59 °F) and 10–18 °C (50–64 °F) respectively. Rivers and mountain-fed streams, including tributaries of the Melen system, are generally colder and more variable: winter temperatures often sit around 4–8 °C (39–46 °F), spring and autumn commonly range 6–14 °C (43–57 °F) and 8–16 °C (46–61 °F), while peak summer warms flowing waters to roughly 12–20 °C (54–68 °F) depending on depth and shading.
Swimming opportunities in Düzce’s lakes and rivers are mixed and depend on location, season and regulation. Informal swimming in lakes can be feasible in warm summer months when surface temperatures rise, but many wetland sites are protected for wildlife or used for water supply, so access may be restricted. Rivers are often unsuitable or discouraged for bathing because of cold temperatures, strong currents, variable depths and occasional contamination or water-management concerns. Visitors should follow local signage and authorities’ guidance before entering any inland water body.
