*** 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 Detroit River near Tecumseh, Ontario, experiences significant seasonal temperature fluctuations, although its large volume and flow from Lake Huron help to moderate extremes. In the winter months, the river water is near freezing, typically ranging from 0∘C to 5∘C (32∘F to 41∘F). During the peak summer season, surface temperatures can warm up, sometimes reaching a comfortable range of 21∘C to 24∘C (70∘F to 75∘F), especially closer to Lake St. Clair. Despite the potential for warmer temperatures, the main river channel is characterized by persistently cool, swiftly moving water.
Swimming in the Detroit River is highly discouraged and exceptionally dangerous, with Tecumseh authorities and the Windsor Port Authority strongly advising against it. The main reasons swimming is not recommended are the extreme current and speed of the water, which is often described as a speedway for shipping, posing a severe drowning risk even for strong swimmers. While designated beaches like Sandpoint in the nearby area are monitored for E. coli bacteria and have seen improved water quality, swimming outside of supervised areas is strictly at one's own risk and often illegal under Port Authority regulations due to the dangers posed by both the current and heavy shipping traffic.
