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
Maassluis is a city located on the Nieuwe Waterweg, a river that connects the Port of Rotterdam to the North Sea. The water temperature in the Nieuwe Waterweg varies with the seasons, with summer temperatures generally ranging from 17°C to 20°C (63°F to 68°F), making it moderately comfortable for swimming, though some may find it a bit chilly. In winter, the temperature drops significantly, often falling to around 4°C to 6°C (39°F to 43°F), which makes swimming unsafe and unpleasant.
Swimming in the Nieuwe Waterweg is generally not recommended due to the river's strong currents, busy shipping lanes, and proximity to the sea. The waterway is heavily trafficked by large vessels, and the conditions can change rapidly due to tides and the movement of ships. While there are no official swimming areas along the Nieuwe Waterweg in Maassluis, nearby beaches or designated swimming areas along the coast provide safer environments for recreational swimming. It's important to be cautious and to check local regulations and water quality reports before swimming in natural waters.
