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
Trebinje, the southernmost city in Bosnia and Herzegovina, is closely linked to the Trebišnjica River, one of the longest sinking rivers globally. The river's flow is heavily regulated by hydroelectric power systems, but in the urban area, its wide, calm course provides a refreshing focal point for the Mediterranean climate city. In winter, the river maintains a cool temperature range, generally between 12∘C and 14∘C. However, the summer heat significantly warms the slower-moving surface water, resulting in comfortable swimming temperatures that often peak between 22∘C and 26∘C in July and August.
Swimming in the Trebišnjica River is a highly popular and encouraged activity within Trebinje, serving as the city's main summer cooling spot. Designated bathing areas, like those near the historic center, are well-established and monitored for water quality, which is generally rated as excellent. The calm flow and pleasant summer warmth, coupled with the clean, mountain-karst water source, make the Trebišnjica a safe and attractive natural destination for locals and tourists seeking aquatic recreation.
