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 Lužnice River flows through South Bohemia and is known for its meandering course, calm stretches, and inviting spots for bathing. Because it is a flowing river, the water temperature is usually cooler than in nearby ponds, but during the warmest summer months it often reaches 19–22 °C, which feels refreshing yet comfortable on hot days. In shallow sections and slow-moving meanders, the water can warm a bit more, making those areas especially pleasant for swimming.
Swimming in the Lužnice is popular among locals and visitors who enjoy natural bathing without the crowds of managed lakes. The riverbanks often provide easy access to the water, with sandy or grassy areas that are suitable for resting and sunbathing. While the current is generally gentle, some spots may feel livelier, giving swimmers both a relaxing and invigorating experience. Altogether, the Lužnice offers a mix of cooler river bathing and peaceful natural surroundings, ideal for those who prefer authentic outdoor swimming.
