*** 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 Hnilec River flows through the Slovak Paradise and the Spiš region, making it a typical mountain river with clear and fresh water. Because of its altitude and the fact that it is fed by smaller streams from the hills, the water remains relatively cold for most of the year. Even in summer, temperatures often stay between 14–18°C, rising slightly higher only in calmer and shallower stretches. This makes the river refreshing, but not particularly warm for longer swimming.
Swimming in the Hnilec is not very common, as it is more popular for fishing and as a scenic part of nature tourism. Locals sometimes use it for a quick dip on very hot days, but due to its cool temperature and stronger flow in some areas, it is better suited for short refreshment than for relaxed bathing. Its charm lies more in the natural beauty and freshness of the water than in classic swimming opportunities.
