*** 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 Hron River, one of the major rivers of central Slovakia, flows through valleys and lowlands where its water temperature changes significantly with the seasons. In summer, during warm weather, the river can reach 19–23°C in calmer stretches, offering refreshing but still comfortable conditions for a swim. In spring, however, the Hron remains much colder, often between 10–15°C, as it carries meltwater from the surrounding mountains. After heavy rains, the temperature can drop quickly due to increased flow and colder inflows.
Swimming in the Hron is more of a local tradition than a mainstream tourist activity. People often use quieter side-arms, gravel banks, or slower parts of the river to cool down on hot days. While it may not have the facilities of lakes or reservoirs, the Hron provides a natural and authentic setting for short swims, with its clear current and scenic surroundings.
