*** 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 Ottawa River, which flows past Gatineau, is a large, flowing body of water influenced by cold headwaters, but its temperature is also affected by warm summer air. In the winter, the water is near freezing, typically around 0∘C to 5∘C (32∘F to 41∘F), with extensive ice cover. In the peak summer season, surface temperatures can warm up considerably, sometimes reaching a range of 21∘C to 24∘C (70∘F to 75∘F), making the beaches suitable for swimming.
Swimming is generally permitted and popular at designated locations in Gatineau, such as Parc des Cèdres and Parc Moussette, both of which feature sandy beaches on the Ottawa River. These municipal beaches are monitored for water quality, but the City of Gatineau typically tests less frequently than its neighbor, Ottawa. Swimming is usually allowed unless water quality advisories are posted due to high E. coli levels, often occurring after heavy rainfall when sewage runoff can enter the river. Outside of these designated and marked swimming areas, swimming is at one's own risk, and caution is advised due to hidden debris and the river's currents.
