*** Forecast - Our water temperature forecast
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 Nieuwe Merwede is a branch of the Rhine-Meuse delta in the Netherlands, connecting the Biesbosch National Park with the Hollands Diep. The water temperature in the Nieuwe Merwede varies seasonally. In winter, it ranges from 4°C to 8°C (39°F to 46°F), while in summer, it can reach 16°C to 22°C (61°F to 72°F), depending on weather conditions and water flow.
Swimming in the Nieuwe Merwede is generally discouraged due to the strong currents, fluctuating tides, and frequent passage of commercial vessels.
