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 Beneden Merwede is a major river in the Netherlands that forms part of the lower course of the Merwede River, flowing through the province of South Holland. The water temperature in the Beneden Merwede typically ranges from 8°C to 12°C (46°F to 54°F) during the colder months, rising to between 18°C and 22°C (64°F to 72°F) during the summer months. These temperatures can be suitable for swimming in the summer, but they remain relatively cooler compared to lakes or smaller rivers in the country.
However, swimming in the Beneden Merwede is generally not recommended due to strong currents, significant shipping traffic, and potential pollution in some sections. The river serves as an important waterway for large vessels, which can make swimming dangerous due to the fast-moving waters and the risk of collision with boats. Additionally, certain areas of the river may have water quality concerns due to industrial activity, which can affect its safety for recreational swimming. It is always advisable to swim in designated swimming areas where water quality is monitored, and where safety measures are in place to protect swimmers.
