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
The Hollands Diep is a broad estuarine river in the Netherlands, connecting the Rhine-Meuse Delta to the Haringvliet. Its water temperature varies throughout the year, typically ranging from 5°C to 10°C (41°F to 50°F) in winter and 15°C to 20°C (59°F to 68°F) during the summer months. Due to its connection to tidal influences from the North Sea, the water temperature can fluctuate slightly depending on the tides and weather conditions.
Swimming in the Hollands Diep is not officially designated, and caution is advised. The river is known for its strong currents, varying depths, and active shipping traffic, making it less suitable for casual swimming. However, the area around the Hollands Diep offers several recreational spots, and nearby lakes and beaches are better equipped and safer for swimming. For water enthusiasts, it’s a popular location for boating and fishing, but those considering swimming should prioritize safety and check local guidelines.
