*** 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
Herstal is a city located in the Wallonia region of Belgium, situated on the banks of the Meuse River. The water temperature in the Meuse River varies seasonally, with warmer temperatures in the summer and cooler temperatures in the winter. In the summer months, the river's water temperature can reach 18°C to 22°C (64°F to 72°F), which is relatively comfortable for outdoor activities such as swimming, though it can still feel cold due to the river's flow and depth. Swimming in the Meuse River is not commonly practiced, as the current can be strong, and there are concerns about water quality, especially in urban areas. The Meuse is more commonly used for boating, fishing, and sightseeing. In winter, the water temperature can drop significantly, typically ranging from 4°C to 7°C (39°F to 45°F), making swimming unsafe due to the cold water and the swift current.
