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
Krnov is a town in the Moravian-Silesian region of the Czech Republic, situated along the Opava River. In this area, the river is relatively calm but remains fairly cool due to its mountain-fed sources. During the summer months of July and August, water temperatures near Krnov generally reach around 17–21 °C, making it suitable for brief dips or wading. In spring and early summer, the water is colder, usually between 10 °C and 16 °C, so swimming at that time can feel brisk.
Swimming opportunities directly in the Opava River at Krnov are limited, as the riverbanks are mostly natural with few formal swimming areas or lifeguard services. Some locals may use calm sections for quick cooling-off dips, but caution is important due to variable currents and occasional boat traffic. The river is more suited for wading, relaxing by the water, or other recreational activities rather than extended swimming.
For more comfortable and safer swimming, residents often visit nearby ponds, small lakes, or recreational reservoirs, which tend to have warmer water and more accessible shores. Overall, the Opava River in Krnov provides a quiet and natural spot for short swims and cooling off, but it is not ideal for regular or long-term swimming activities.
