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 Třemošná River, located near the town of the same name in the Plzeň Region of the Czech Republic, is a small, tranquil watercourse that flows through rural and lightly forested areas. In the warmer months, especially July and August, shallow parts of the river can reach temperatures of around 18–20 °C, offering a refreshing option for a quick dip. However, due to its modest size, the river can feel quite cool in deeper or shaded sections, so swimming is generally limited to the sun-exposed shallows.
The riverbanks are mostly natural, with grassy or slightly muddy edges, so there are no formal swimming facilities. This makes Třemošná more suitable for wading, short swims, or dipping feet into the water rather than extended swimming sessions. Families and locals often use it as a quiet spot to cool off during hot days, enjoying the peaceful surroundings away from crowded recreational areas.
Besides swimming, the Třemošná River is appreciated for light outdoor activities such as picnicking, nature walks, and observing local wildlife. Its gentle flow and serene environment create a relaxing summer experience, even though the swimming opportunities are modest and mostly informal.
