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
Vrutak Lake (Jezero Vrutak) is an artificial water reservoir located on the lower course of the Trebišnjica River in Herzegovina. It is primarily an accumulation for hydro-power, which influences its thermal regime. The water in the reservoir is generally cool throughout the year due to its river source. In winter, temperatures are low, typically ranging from 8∘C to 12∘C. During the peak summer months, the surface layer warms up, but usually remains fresh, with temperatures reaching approximately 19∘C to 22∘C, depending on the water level and flow.
Swimming in Vrutak Lake is generally not encouraged or officially promoted, as its primary purpose is power generation, and it is a controlled water reservoir. The lake does not have designated public beaches or tourist infrastructure for swimming. While there are no strict, permanent prohibitions against entering the water, the lack of official swimming areas, coupled with fluctuating water levels and potential hidden dangers associated with reservoir operations, means that any recreational use, including swimming, is undertaken at the visitor's own risk.
