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
The town of Bileća in Bosnia and Herzegovina is situated near the source of the Trebišnjica River, but its most significant water body today is the large, artificial Bileća Lake, formed by damming the river. The river itself, due to its karstic origin, is known for its cold temperature year-round. Before the damming, the water was always quite cold. In the lake, which is deep, temperatures vary from a cold 8∘C to 12∘C in winter, to a warmer surface layer in summer, which can reach 20∘C to 23∘C in August, making it refreshing for swimming.
Swimming is generally permitted in Bileća Lake and is popular during the summer at various access points, as the lake provides the main opportunity for water recreation in the area. However, it is important to note that the river Trebišnjica itself, both upstream and downstream of the lake, often maintains a much colder temperature due to its spring origin. The lake is a major regional attraction for diving, fishing, and general recreation, with no official restrictions on swimming, although safety precautions for a large reservoir should always be followed.
