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 Jablonec nad Nisou, the Lusatian Neisse River flows through a hilly and forested area, giving the water a naturally cool character. Because the river collects water from higher elevations, temperatures remain on the lower side even in summer. In late spring, the water usually ranges around 14–16 °C, while in July and August it can reach 17–19 °C on warm days. This makes the river refreshing but relatively cold, so swimming is often short and invigorating rather than long and leisurely.
Swimming in the Lusatian Neisse directly within Jablonec nad Nisou is limited, as the riverbanks in the urban area are not developed for bathing. However, some locals take advantage of shallow and calm sections along the river for quick dips. The current is gentle in these stretches, making wading or short swims possible, but swimmers need to be cautious and mindful of the cooler temperature.
For a more comfortable bathing experience, residents often visit nearby ponds or small recreational lakes where the water warms more quickly. Still, the Lusatian Neisse offers a natural and refreshing option for those who enjoy colder river water and a quiet, scenic environment, particularly on hot summer days.
