*** 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
Mount Pearl, Newfoundland and Labrador, is located on the Avalon Peninsula, where lakes and rivers are strongly influenced by the cool maritime climate. Freshwater bodies in and around the city, such as Mundy Pond, generally remain quite cold. Based on long-term data for a nearby monitoring station, the mean summer temperature for Mundy Pond is approximately 13∘C (55∘F). Even in the peak summer months, surface water temperatures in small ponds and rivers are unlikely to rise much above 18∘C (64∘F). In the winter, the water is near freezing, typically dropping to the range of 0∘C to 5∘C (32∘F to 41∘F), leading to ice cover.
Swimming in the natural water bodies of Mount Pearl is generally discouraged due to the persistently cold temperatures and lack of designated, supervised areas. The water temperature poses a year-round risk of cold shock and hypothermia for sustained swimming. Furthermore, local authorities do not promote swimming in the natural lakes or the Waterford River that runs through the city; instead, the municipality provides safe, supervised swimming at the Summit Centre Aquatic Centre. Therefore, any swimming in the local ponds or rivers is strictly at one's own risk, with strong caution advised due to the frigid water.
