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
Bihać, located in the northwest of Bosnia and Herzegovina, is beautifully set on the banks of the Una River, known for its crystal-clear turquoise water and strong currents. The temperature of the Una changes notably with the seasons. In winter, it drops to about 4–6°C, while in spring it gradually warms to around 10–14°C. During the summer, when Bihać experiences warm continental weather, the river reaches 18–22°C, occasionally rising to 24°C in calm periods. In autumn, it cools again to around 10–15°C as the air temperature decreases.
Swimming in the Una is popular among locals and visitors, especially near calmer sections and river beaches. The water is clean and refreshing, but even in summer it feels cool because of the river’s mountain origin. Official swimming is allowed in designated zones, while other areas with strong currents or rapids are better suited for rafting and kayaking. Overall, the Una River offers one of the most scenic and enjoyable freshwater swimming experiences in Bosnia and Herzegovina.
