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 Hollandse IJssel is a river in the western Netherlands, flowing through the provinces of South Holland and Utrecht. It serves as a major drainage system, connecting various smaller waterways with the larger rivers in the region, including the Lek and the Oude Maas. The water temperature in the Hollandse IJssel typically varies depending on the season, with summer temperatures reaching around 15°C to 20°C (59°F to 68°F). In the winter months, the water temperature can drop to about 4°C to 6°C (39°F to 43°F), making it quite cold and less suitable for swimming.
Swimming in the Hollandse IJssel is not generally recommended due to water quality concerns. The river passes through urban and industrial areas, which can lead to pollutants and contaminants affecting the water. Strong currents are also common in certain parts of the river, especially near locks and bridges, making it dangerous for swimmers. If you're looking to swim in the region, it's safer to visit designated swimming spots or lakes where the water is regularly monitored for quality and safety.
