Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
The Fraser River near Delta, located at the river's mouth where it enters the Strait of Georgia, is a large, high-volume waterway with consistently cold temperatures. Due to its size and mountainous origins, even in the peak summer months, surface temperatures typically only reach a maximum range of 17∘C to 20∘C (63∘F to 68∘F), with historic averages peaking around 18.2∘C (64.8∘F). These temperatures pose a significant risk of cold shock and hypothermia for all but the hardiest, brief immersions. In the winter, the water is much colder, typically ranging from 4∘C to 10∘C (39∘F to 50∘F).
Swimming in the Fraser River near Delta is strongly discouraged and highly dangerous. The river's primary function as a major shipping channel, combined with its tremendous flow rate, creates powerful and unpredictable currents and undertows that are often hidden by the murky, silt-laden water. Furthermore, the river carries debris, including large logs, which pose a severe collision hazard. There are no official, lifeguarded areas, and primary-contact recreation such as swimming is not common, with local health authorities monitoring water quality for E. coli that can sometimes exceed safe limits. Any swimming is strictly at one's own risk due to the hydraulic and temperature hazards.
