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 Boven Merwede is a significant river in the Netherlands, located in the province of South Holland. It is part of the Merwede river system, which is formed by the confluence of the rivers Waal and Nederrijn. The water temperature in the Boven Merwede typically ranges from 6°C to 10°C (43°F to 50°F) in the colder months and can rise to around 18°C to 22°C (64°F to 72°F) during the summer. These temperatures are considered too cool for comfortable swimming in the colder seasons, but more suitable for swimming during the warmer months, especially when the water temperature is at its peak in summer.
However, swimming in the Boven Merwede is not advised for several reasons. The river has strong currents, and the waterway is frequently used by large commercial vessels, which poses a significant danger to swimmers. The fast-moving water, combined with the risk of boat collisions, makes it unsafe for recreational swimming. Additionally, water quality in the Boven Merwede can vary, especially near industrial areas, where pollution may affect the river's cleanliness and safety for swimming. For these reasons, it's best to choose designated swimming locations with controlled water quality.
