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
Nechranice Lake, located in northwestern Bohemia, is one of the largest reservoirs in the Czech Republic and is well known for its wide water surface. Because of its size, the water warms up more slowly compared to smaller ponds, but during the height of summer it usually reaches comfortable swimming temperatures of around 20–23 °C. On particularly hot days, the shallow bays can get even warmer, making them more inviting for bathers, while the open parts of the lake remain slightly cooler.
Swimming in Nechranice is possible in several designated spots, often with beaches or grassy banks suitable for sunbathing. The large expanse of the lake also makes it popular not only for swimming, but for water sports such as windsurfing, sailing, and paddleboarding. Families often come here to spend the whole day by the water, enjoying the combination of refreshing swimming conditions and the open landscape around the reservoir. It is a good choice for those looking for both relaxation and a bit of activity on the water.
