*** 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.

The Detroit River, a vital waterway connecting Lake St. Clair and Lake Erie, has a significant role in the Great Lakes system. Its water temperature varies seasonally, with cold winter months seeing temperatures close to freezing, while summer brings warmer waters ranging between 65°F and 75°F (18°C–24°C). Despite these comfortable summer temperatures, the river's industrial history and urban surroundings can impact water quality, making it less ideal for direct recreational swimming in many areas.
Swimming in the Detroit River is generally discouraged due to strong currents, heavy boat traffic, and concerns over water cleanliness in some sections. However, the river is a hub for other recreational activities, such as boating, fishing, and sightseeing. Waterfront parks and designated beaches along Lake St. Clair or Lake Erie offer safer and more enjoyable swimming opportunities nearby, while the river itself remains a scenic attraction for those looking to experience its beauty from the shore or on the water.
