*** 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.

Location & Local Information

In Košice, the Hornád River flows directly through the city, giving it both a scenic and practical significance. The water temperature here is influenced by the river’s mountain origin and relatively fast current. In summer, during warm and dry periods, the Hornád in Košice can reach around 18–21 °C, but after rain or colder nights the temperature quickly drops, making the water feel fresh even in July or August. Compared to lowland lakes, it never warms up to very high levels, and its variability is part of its natural character.

As for swimming, the Hornád within Košice is not a designated bathing area. The current can be strong, and the urban environment makes it less suitable for regular swimming. Nevertheless, locals sometimes use calmer shallows or side arms of the river for short dips or to cool down in hot weather. More often, the river is enjoyed from its banks for relaxation, fishing, or water sports, while those looking for proper swimming typically head to nearby lakes or reservoirs.
