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
In Louny, the Ohře River flows with a steady current and provides a refreshing natural element within the town. During the summer months, the river’s temperature usually rises to around 18–22 °C, depending on the weather and rainfall. Because the Ohře is relatively wide here, the water tends to stay cooler than in small ponds, making it more invigorating, especially on hot days. In spring and early summer, the water can remain below 18 °C, which some swimmers find brisk but manageable for shorter dips.
Swimming in the Ohře at Louny is possible, but it is generally more common in natural spots along the riverbanks rather than in structured bathing areas. Locals often use the quieter sections of the river to cool down, although the current should always be considered. For those who prefer a safer and more comfortable swim, nearby recreational lakes and pools around the town are often chosen. The river itself offers more of a natural and adventurous experience, appealing to those who enjoy direct contact with flowing water.
