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.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Surrey, British Columbia, sits at the meeting point of the Fraser River and the Salish Sea’s Boundary Bay, so water conditions vary by location and season. Coastal and bay waters around Surrey typically register about 6–9 °C in winter. In spring temperatures commonly rise into the 7–12 °C range as the air warms and daylight increases. Summer is the warmest period for swimming, with surface temperatures generally between 13–17 °C and, in shallow, sheltered spots on hot afternoons, occasionally reaching 18–20 °C. By autumn the water cools again, moving back toward 10–13 °C. River temperatures in the Fraser can be colder and more changeable than bay waters, and shallow tidal flats warm more quickly than deeper channels.

Swimming Conditions
Swimming opportunities in Surrey reflect those mixed conditions. Public beaches such as Crescent Beach and areas around Semiahmoo Bay offer accessible sand and family-friendly shorelines, but the water remains refreshingly cool even in summer, so many visitors swim briefly or use wetsuits for longer swims. The Fraser River and certain shorelines can have strong currents and boat traffic, making them unsuitable for casual swimming; lifeguarded and supervised spots are the safest choice during summer months. For those preferring warmer or more controlled environments, Surrey’s community pools and aquatic centres provide year-round swimming. Wildlife viewing, walking along tidal flats, paddle sports in calm bays, and nearby beaches in adjacent municipalities expand options for a beach holiday while taking into account the typically cool local water temperatures.
