*** 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
Uccle is a district of Brussels, Belgium, located along the Senne River. The water temperature in the Senne River fluctuates throughout the year, being cooler in the winter and warmer in the summer. During the summer months, the water temperature typically ranges from 15°C to 20°C (59°F to 68°F), which may seem suitable for swimming in calmer sections of the river. However, swimming in the Senne is not a common activity and is generally not recommended. The river has suffered from significant pollution in the past due to industrial runoff and wastewater from the city, and while there have been efforts to improve water quality, concerns remain. The Senne is more often used for activities such as small-scale boating, fishing, and as an element of urban nature, but it is not considered a safe or popular destination for recreational swimming. During the winter, the water temperature drops to between 4°C and 7°C (39°F to 45°F), making swimming dangerous due to the cold temperatures and potential risks from strong currents.
