*** 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
Gradačac is located in the northeastern part of Bosnia and Herzegovina, known for its surrounding lakes and small rivers rather than large waterways. The most notable are Hazna Lake and Vidara Lake, both artificial reservoirs that serve as popular recreation spots. Water temperatures in these lakes follow a mild continental pattern, dropping to around 3–6 °C in winter and warming to 22–26 °C in summer. During the warmest months, the surface water can even reach 28 °C on sunny days, making them pleasant for swimming and other water activities.
Swimming is allowed in both lakes, especially in designated areas where the depth and cleanliness are suitable. Local residents and visitors often swim, fish, and enjoy small boats or pedalos from June to September. Smaller rivers in the region, such as tributaries of the Spreča, remain cooler, with summer temperatures around 18–21 °C, so they are used mainly for short refreshing dips. The calm surroundings, green banks, and clean water make the Gradačac area a favored place for summer recreation and family relaxation.
