*** 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.

Location & Local Information
Zaventem is a town located in the Flemish region of Belgium, near Brussels, and lies along the Woluwe River, a tributary of the Senne. The water temperature in the Woluwe River fluctuates throughout the year, with cooler temperatures in the winter and warmer ones in the summer. During the warmer months, the water temperature typically ranges from 15°C to 20°C (59°F to 68°F), which could be tolerable for swimming in the calmer parts of the river. However, swimming in the Woluwe River is not common or recommended in Zaventem. The river flows through urban and suburban areas, where it is often affected by pollution from runoff, industrial waste, and sewage. These factors can significantly degrade water quality, making the river unsafe for recreational swimming. In the winter months, water temperatures drop to around 4°C to 7°C (39°F to 45°F), which, combined with strong currents, makes swimming both uncomfortable and dangerous.
