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
Velešín is a small town located near the shores of the Římov Reservoir (Vodní nádrž Římov) in the South Bohemian Region of the Czech Republic. The reservoir is primarily used for water supply and flood control, which means that swimming is limited and regulated in many areas. During the peak summer months of July and August, water temperatures near Velešín can reach around 20–22 °C in accessible spots, providing conditions that are comfortable for swimming where it is allowed. The calm waters in certain sections make brief dips or wading enjoyable, especially in quieter zones along the shoreline.
Swimming near Velešín is mostly informal and takes place in areas where regulations permit, with natural banks rather than fully developed beaches. Visitors often combine a swim with picnics, walking along the water’s edge, or other recreational activities. The reservoir’s scenic surroundings, including forests and gentle hills, create a tranquil environment that is ideal for relaxing by the water.
Outside the peak summer period, water temperatures drop significantly. In May or September, the reservoir usually remains around 14–16 °C, which is generally too cool for extended swimming but still allows brief wading or splashing near the shore.
