*** 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
Chilliwack, situated in the fertile Fraser Valley of British Columbia, lies along the southern banks of the Fraser River, where the water temperature changes noticeably with the seasons. In early spring, when snowmelt from the interior mountains begins, the river remains very cold, typically between 37–43°F (3–6°C). As temperatures rise through May and June, the Fraser near Chilliwack warms slightly to around 50–57°F (10–14°C). During midsummer, from July through August, shallow or slow-moving sections of the river may reach 63–68°F (17–20°C), while the main channel stays cooler due to its depth and flow rate. By late September, the water cools again, often dropping below 55°F (13°C) as the season transitions into autumn.
Swimming in the Fraser River near Chilliwack is possible but generally discouraged because of the river’s powerful current, fluctuating water levels, and cold temperature. Even during the warmest months, the flow remains strong enough to pose risks to inexperienced swimmers. Those who wish to cool off in the water typically visit nearby lakes such as Cultus Lake or Chilliwack Lake, where the conditions are warmer and safer. While the Fraser River offers scenic beauty and opportunities for boating and fishing, it is best appreciated from the shore rather than as a location for recreational swimming.
