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 Otava River, flowing through the South Bohemian Region of the Czech Republic, is a medium-sized river known for its calm stretches and scenic surroundings. During the summer months, shallow, sun-exposed areas of the river can warm up to around 19–22 °C, offering a refreshing opportunity for swimming and wading. While these sections are comfortable for a quick dip, deeper parts of the river remain cooler, so longer swims may feel brisk, especially in shaded areas.
The riverbanks along the Otava are mostly natural, with grassy edges, pebbly spots, and occasional sandy areas providing informal access to the water. There are no official swimming beaches or lifeguards, so visitors should be cautious and choose shallow, calm sections for safe swimming. Families with children often favor these areas, where the water is gentler and easier to navigate.
Besides swimming, the Otava River is popular for recreational activities such as kayaking, canoeing, and fishing. Its combination of flowing water, picturesque landscapes, and relatively quiet surroundings makes it an appealing spot for spending a summer day outdoors, offering a mix of relaxation and light water recreation.
