*** 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

The Kráľová Reservoir, situated on the Váh River between Sereď and Šaľa, is one of the larger lowland water bodies in Slovakia. Thanks to its location and relatively shallow average depth, the water here warms up quickly in summer. During hot spells in July and August, temperatures often reach 22–25 °C, creating pleasant conditions for bathing and water sports. In spring or after prolonged rain, the water can be cooler and slightly more dynamic due to the river inflow, but the reservoir usually stabilizes to comfortable levels by early summer.

Swimming is possible at several natural access points, though the area is better known for fishing, boating, and windsurfing. The wide surface and open surroundings give it the feel of a large lake rather than a river reservoir. While there are no extensive sandy beaches, locals and visitors often find spots along the banks to swim, sunbathe, or simply cool down. It is a good option for those looking for natural swimming in western Slovakia outside the crowded urban lakes.
