*** 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
Coquitlam, located within the Metro Vancouver region of British Columbia, borders the lower Fraser River, where the water temperature reflects both the influence of snowmelt from the interior and the moderating effect of the coastal climate. In early spring, the Fraser River remains cold, averaging around 39–43°F (4–6°C) as runoff from melting snow and glaciers enters the system. By late May and June, temperatures rise to approximately 50–57°F (10–14°C), though the water still feels chilly. During midsummer, from July through August, the river near Coquitlam reaches its warmest levels, typically between 63–68°F (17–20°C) in calm, shallow stretches. By autumn, cooling air and increased rainfall lower the temperature again, often to below 55°F (13°C) by late September.
Swimming in the Fraser River near Coquitlam is technically allowed but not recommended because of strong currents, deep channels, and cold water even in summer. The river’s flow varies with tides and upstream runoff, creating unpredictable conditions for swimmers. While some residents may wade in sheltered areas on hot days, most prefer nearby lakes such as Buntzen Lake or Sasamat Lake, which offer warmer water and designated swimming beaches. The Fraser River remains better suited for scenic enjoyment, fishing, and boating rather than for recreational swimming.
