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
Kalisz, one of the oldest cities in Poland, is situated on the Prosna River, which weaves through its historic heart. The river’s water temperature in summer typically ranges between 18°C and 22°C, making it moderately cool and refreshing. While the Prosna is not widely known for swimming, there are informal spots along its banks where locals sometimes enjoy a quick dip during the warmer months. However, swimming should always be approached with caution due to the lack of lifeguarded areas.
The river serves more as a scenic and recreational feature than a primary swimming location. Canoeing and paddleboarding are more popular activities along the Prosna, offering a relaxing way to explore Kalisz’s natural and urban landscapes. Its calm waters and picturesque surroundings make the Prosna a cherished part of the city's leisure culture.
