Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 65°F (18°C) to 68°F (20°C). This is already quite warm water, which is ideal for most people. Swimming becomes comfortable, and prolonged stays in the water do not cause discomfort. This temperature is perfect for family trips and for those who prefer warmer water. It is also comfortable for water sports such as surfing or swimming. 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
The Red River of the North, which flows through Winnipeg, is a large, slow-moving prairie river with temperatures heavily influenced by the extreme continental climate. In the peak summer months, the surface water can warm up considerably, typically reaching a comfortable range of 21∘C to 26∘C (70∘F to 79∘F), making it one of the warmer rivers in the region. Conversely, in the winter, the river is near freezing, with temperatures often around 0∘C to 3∘C (32∘F to 37∘F), and the entire surface is frozen for months.
Swimming in the Red River in Winnipeg is strongly discouraged by local authorities and is generally considered unsafe. Although the river is not explicitly closed to swimmers, there are no designated swimming areas or lifeguards. The primary reason for caution is poor water quality, which frequently includes high levels of E. coli bacteria due to combined sewer overflows and runoff, often resulting in official water quality advisories. Additionally, the river carries debris, and the currents, while slow at times, can be unpredictable and hazardous, especially after heavy rains. Any decision to swim is therefore entirely at one's own risk, and residents are directed toward safer, supervised swimming facilities.
