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
Belmont Lake, situated in the Havelock-Belmont-Methuen area of Ontario, is a recreational lake with water temperatures that fluctuate significantly with the seasons. In the cold winter months, the lake freezes completely, with water temperatures near the freezing point, generally ranging from 0∘C to 5∘C (32∘F to 41∘F). Due to the warmth of the summer in this inland region, the lake warms up considerably in the peak season, with surface temperatures typically reaching a comfortable range for swimming, likely peaking between 20∘C and 24∘C (68∘F to 75∘F).
Swimming is widely permitted and popular throughout Belmont Lake, with resorts, campgrounds, and private cottages all utilizing the water for recreational activities. The lake features beaches, such as the one associated with Belmont Lake Provincial Park or local municipal access points, confirming its status as a designated swimming site. However, most public access points on the lake are typically unsupervised, meaning there are no official lifeguards on duty. All swimming is therefore strictly at one's own risk, and users should be cautious of boat traffic and the potential for water quality advisories during the warmest part of the summer, as issued by Peterborough Public Health.
