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
In Brno, the Svratka River winds its way through the city and offers a few natural spots where people can cool off, although it is not as widely used for bathing as the nearby Brněnská přehrada reservoir. The water temperature of the Svratka within Brno is shaped by its steady flow and shaded riverbanks, so even in midsummer it usually stays cooler than standing lakes, often around 18–21 °C during hot periods. This makes swimming in the river refreshing and sometimes a bit brisk compared to the warmer reservoirs in South Moravia.
Despite the cooler conditions, some stretches of the Svratka in Brno are popular for informal bathing, especially on very warm days. Locals enjoy entering the river from grassy or pebbly banks, and the natural current adds a dynamic feel to swimming. While it lacks the infrastructure of designated swimming areas, the Svratka within Brno still provides an authentic and simple way to experience water recreation right in the city, especially for those who prefer a quick dip in cooler, flowing water.
