*** 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 Vltava River, the longest river in the Czech Republic, flows through diverse landscapes from the Bohemian Forest to Prague and beyond. In summer, water temperatures in many stretches of the river usually range between 18–23 °C, making it suitable for swimming and wading in calmer areas. In spring and early autumn, the water tends to be cooler, often around 13–17 °C, so bathing is more refreshing and generally limited to short dips for most people.
Swimming in the Vltava is mostly informal, with locals and visitors using grassy riverbanks, shallow inlets, and quieter sections of the river for a dip. Some reservoirs and calmer stretches, like those near Slapy or Orlík, offer more organized access and safer conditions for families. In urban areas such as Prague, swimming is less common due to boat traffic and river flow, while rural sections provide more natural and peaceful spots to enjoy the water.
The river’s flow varies along its course, with faster currents near dams and narrower channels, so swimmers need to be mindful of safety and choose calmer areas for bathing. Beyond swimming, the Vltava is popular for boating, kayaking, and fishing, which makes it a central recreational feature of the country. Its combination of scenic surroundings, natural beaches, and moderate summer temperatures offers an authentic and refreshing water experience across the Czech Republic.
