*** 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 Grand River, flowing through Brantford, Ontario, is a large, historically significant river whose water temperature experiences significant seasonal changes. In the cold winter months, the river drops to near freezing, typically ranging from 0∘C to 5∘C (32∘F to 41∘F), with ice common in the slower-moving sections. During the peak summer season, the surface water can warm to a comfortable range, generally between 19∘C and 24∘C (66∘F to 75∘F), which is suitable for brief water contact.
Direct swimming in the Grand River within the limits of Brantford is prohibited by municipal bylaw due to significant safety concerns. The main hazards are the river's unpredictable flows, strong currents, and the inherent dangers around the various dams and weirs, which create powerful undertows. Instead of river swimming, the city and the Grand River Conservation Authority (GRCA) promote safe, controlled water recreation. Brant Conservation Area, located nearby, features one of the province's largest supervised swimming pools, which is open during the summer and provides a clean, safe alternative for swimming.
