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
Údolní nádrž Jesenice, located near Cheb in western Bohemia, is one of the warmer reservoirs in the region thanks to its relatively low altitude and sheltered setting. During June, water temperatures usually range between 19–21 °C, while in July and August they often climb to 23–25 °C, with the warmest days even reaching 26 °C. This makes it one of the more reliable spots in the area for comfortable swimming throughout the summer season.
The reservoir is well known for recreation, and its long shoreline provides many opportunities for swimming. There are both organized beaches with facilities and quieter stretches where people can enter the water from grassy banks. Because of its size, Jesenice also attracts those who enjoy paddleboarding, sailing, or other water sports, but there is still plenty of space for casual swimmers. On hot summer days, the combination of warm water and natural surroundings makes it a popular place for both locals and visitors to relax and cool off.
