*** 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
The Brussels Canal, flowing through the capital of Belgium, connects the city to the Scheldt River and serves as a crucial part of Brussels’ waterway infrastructure. The water temperature in the Brussels Canal varies depending on the time of year, with colder temperatures in the winter months averaging around 5-7°C (41-45°F) and warmer temperatures in the summer, reaching approximately 18-22°C (64-72°F). While summer temperatures can be more inviting, the canal remains relatively cool even during the warmest months due to the water’s exposure to urban runoff and environmental factors like rainfall and pollution.
Swimming in the Brussels Canal is not recommended. Due to its location in the heart of the city, the canal’s water quality is often impacted by pollution from surrounding industries, urban runoff, and boat traffic. The canal’s slow-moving water can also lead to stagnation in certain areas, further reducing its suitability for recreational activities like swimming. The Belgian authorities advise against swimming in the canal for health and safety reasons, as it may contain harmful contaminants. However, the canal is used for other activities, such as boat tours and kayaking, which are more suitable and enjoyable for visitors.
