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
Olsztyn, the capital of the Warmian-Masurian Voivodeship in Poland, is situated along the Łyna River, which runs through the city. While the Łyna River is known for its scenic beauty, it is not primarily used for swimming. The water temperature in the Łyna River during the summer months typically ranges from 15°C to 20°C, which can be quite cool for those seeking a leisurely swim. The water conditions can also vary depending on the season, rainfall, and other environmental factors, making it important to check for suitability before entering.
Although there are no designated swimming areas along the river, some residents and visitors choose to enjoy the Łyna River for activities like kayaking, fishing, or simply walking along its banks. The river's calm sections make it a good spot for kayaking and canoeing. However, due to the potential for fast currents and the varying water levels, it’s not the ideal place for a relaxing swim. For safer swimming options, people in Olsztyn typically prefer local lakes, swimming pools, or designated beach areas.
