*** 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
Milton, Ontario, is not situated on a Great Lake, but rather features several inland water bodies, most notably the reservoir at Kelso Conservation Area and Sixteen Mile Creek. These freshwater sources experience a significant temperature range. In the cold winter months, all local water bodies are either frozen or near freezing, typically ranging from 0∘C to 5∘C (32∘F to 41∘F). During the peak summer season, particularly in the shallower Kelso Reservoir, surface water warms considerably, generally reaching a comfortable range of 20∘C to 24∘C (68∘F to 75∘F).
Swimming is specifically encouraged at Kelso Conservation Area Beach, which is managed by Conservation Halton. This designated beach on the reservoir is supervised by lifeguards during the summer season, confirming its status as a safe and controlled swimming environment. Conversely, swimming in the fast-flowing Sixteen Mile Creek is not permitted or is strongly discouraged due to safety concerns like strong currents and potential urban runoff. As with any supervised beach, the Kelso reservoir is monitored for E. coli bacteria, and visitors must adhere to any temporary water quality advisories posted by Halton Region Public Health.
