*** 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.

The Demer is a river in Belgium that flows through the province of Flemish Brabant and into the city of Leuven, ultimately joining the River Maas. It spans approximately 90 kilometers and is known for its pleasant natural surroundings, especially in rural areas. The water temperature in the Demer fluctuates throughout the year. During the summer months, the water temperature can rise to 18°C to 22°C (64°F to 72°F), while in the colder winter months, it can drop to around 5°C to 7°C (41°F to 45°F). The river experiences typical seasonal variation, with higher temperatures generally in June through August.
Swimming in the Demer is possible, but not always recommended, especially in urban areas. The water quality can be affected by various environmental factors such as agricultural runoff, urban development, and occasional pollution events. The river is mostly shallow in many areas, with water depths that can make swimming more challenging, especially after periods of heavy rainfall when the water levels may fluctuate. While some sections of the river are suitable for light recreational activities such as kayaking, it is important to be cautious about water quality, particularly in the more industrialized or urban stretches.
