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.

The Oslava River winds through the Vysočina and South Moravian regions, and much like other rivers in this part of the country, its water temperature depends strongly on the season and local weather. In summer, the river usually warms up to around 18–22 °C, but the temperature can shift quickly after rain or cooler nights because of its natural flow and shaded stretches. Compared to larger reservoirs, the Oslava stays on the fresher side, offering water that feels invigorating rather than consistently warm.
When it comes to swimming, the Oslava is best enjoyed in calmer sections where the current is slower and the riverbed more even. These spots are often used by locals to wade, splash, or take short swims, especially on hot days. While it does not provide wide sandy beaches or long stretches for bathing, the river offers a more natural and adventurous swimming experience, surrounded by greenery and quiet landscapes. For those seeking a refreshing dip in a scenic setting, the Oslava can be a rewarding choice.
