❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Montréal, Quebec, is situated along the St. Lawrence River, offering a unique waterfront experience. During the summer months, the water temperature in the river typically ranges from 65°F to 75°F (18°C to 24°C), which can be refreshing but may not be as warm as some other swimming spots in the region. The river's current is usually moderate, making it suitable for activities like swimming, kayaking, and paddleboarding, although the strong flow of water in certain parts of the river can be challenging for casual swimmers.
While the river is used for recreational activities, it is important to note that swimming directly in the St. Lawrence River within the city is not as common due to the water's fluctuating quality and current. However, there are designated beaches and swimming areas in and around Montréal, such as the Jean-Drapeau Park beach, where the water is monitored regularly for safety and cleanliness. In these areas, the water is generally safe for swimming during the summer months when the temperatures are more favorable.
In the cooler months, water temperatures in the St. Lawrence River can drop significantly, often falling to around 33°F to 40°F (1°C to 4°C) by late fall and winter. During this time, swimming is typically not recommended due to the cold temperatures, and the river may freeze in certain spots. However, during the warmer months, Montréal's waterfront remains a vibrant hub for outdoor activities, with the river providing a beautiful backdrop for both locals and visitors.
