*** 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
Aš, located in the westernmost part of the Karlovy Vary Region, is surrounded by a mix of small ponds, streams, and natural reservoirs. Because of the town’s higher elevation and forested surroundings, water in these bodies warms up gradually during the summer. In June, temperatures generally range around 16–18 °C, while in July and August they can reach 20–22 °C, offering a pleasant but refreshing environment for swimming. The waters here are cooler than larger lowland lakes, which makes them especially suitable for those who enjoy invigorating dips.
Swimming opportunities in Aš are mostly tied to small local ponds and designated recreational areas. The banks are often grassy with gentle slopes, making it easy to enter the water for a short swim or wade. These spots are popular with local families and people seeking quiet natural settings, rather than large organized beaches, which adds to the relaxed and intimate atmosphere.
Overall, Aš provides a calm and natural environment for summer bathing. While the water is cooler compared to some southern lakes, the combination of peaceful surroundings and accessible ponds makes it ideal for short swims, cooling off during hot days, and enjoying the outdoors without crowds.
