*** Forecast - Our water temperature forecast
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 Váh is the longest river in Slovakia, stretching from the Tatras down to the Danube. Because it flows through different landscapes, the water temperature varies greatly along its course. In the upper mountain sections, the river is colder, often staying below 15°C even in summer. Further downstream, especially in the lowland regions, the water warms up more quickly, and during July and August it can reach 20–24°C, which makes it suitable for swimming.
Bathing in the Váh is popular mainly in calmer stretches, near river bends or places where the current is weaker. While it is not a classic “beach river,” locals often use it to cool down on hot days. Some areas are better suited for short refreshing swims, while others, especially around reservoirs built on the Váh, provide more comfortable conditions for longer stays in the water.
