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.

The Ploučnice River flows through northern Bohemia, meandering past towns and forests, creating a scenic and peaceful environment. Because much of its water comes from upland streams and small tributaries, the river tends to stay cool even during the summer months. In late spring, water temperatures usually range around 15–17 °C, while in July and August they can reach 18–20 °C on warmer days. This makes swimming refreshing but relatively cool, especially compared to shallow ponds or lakes in the region.
Swimming directly in the Ploučnice is possible in calmer and shallower sections, particularly outside urbanized areas where the banks are more natural. The water is generally clear, and the gentle current in these stretches makes wading or short swims feasible. However, the cooler temperature means it is more suitable for invigorating dips rather than long, leisurely swims.
For a more comfortable bathing experience, many people prefer nearby ponds or recreational lakes where the water warms more quickly. Still, for those who enjoy natural river swimming, the Ploučnice offers a quiet and scenic option, allowing swimmers to combine the experience of fresh, cool water with tranquil surroundings.
