*** 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
Length 12 kilometres (7.5 mi)
The Rupel is a river located in the northern part of Belgium, flowing through the provinces of Flemish Brabant and Antwerp. It is formed by the confluence of the Dender and the Senne rivers and eventually flows into the Scheldt River. The Rupel is a tidal river, and its water temperature can fluctuate significantly based on the season and tidal changes. During the summer months, the water temperature can reach around 18-22°C (64-72°F), which is suitable for swimming, though it is often cooler than other inland rivers due to its connection to the North Sea. In winter, the water temperature typically drops to about 5-7°C (41-45°F), making swimming less appealing during this time.
Swimming in the Rupel is generally not as popular as in other rivers or lakes in Belgium due to its fast currents, industrial surroundings, and the occasional water pollution from nearby urban areas. However, there are certain areas along the river that are calmer and where the water quality is relatively good, making swimming more feasible. It is important to check the water quality and be cautious of the tides and currents, as the river can be quite unpredictable. As a result, swimming is not a widespread activity along the Rupel, but those who are experienced and knowledgeable about local conditions can enjoy the river in some areas.
