*** 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 Little Danube (Malý Dunaj) is a side arm of the Danube that branches off near Bratislava and flows through the lowlands of western Slovakia. Thanks to its calmer flow and shallower sections compared to the main Danube, the water here warms up relatively well in summer. In spring, the temperature is still cool, often under 15°C, but by July and August it can reach 22–25°C in many spots, especially in slower bends and wider stretches. This makes it more comfortable for swimming than the main Danube, which tends to stay colder and more turbulent.
Swimming in the Little Danube is popular in natural settings, particularly in areas with sandy or grassy banks where entry into the water is easy. Locals and visitors use it not only for bathing but also for canoeing and relaxing by the water. While it doesn’t have large official beaches, it offers many natural places for a refreshing dip, especially on hot summer days.
