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
Richmond, a leafy suburb in southwest London, lies along one of the most picturesque stretches of the River Thames. Here, the river is wide, calm, and tidal, with water temperatures that change steadily with the seasons. In winter, the Thames near Richmond typically measures around 5–7°C (41–45°F), remaining quite cold and brisk. By spring, it slowly rises to about 10–13°C (50–55°F), reaching its warmest levels in July and August, when temperatures range between 18 and 21°C (64–70°F). During early autumn, the water cools again to around 14–16°C (57–61°F), maintaining a fresh, mild character well into October. The mixture of tidal and freshwater influences keeps the flow gentle but variable throughout the year.
Swimming in the River Thames at Richmond is permitted in some areas, though it is best suited for experienced wild swimmers due to changing tides and boat traffic. The water is generally clean enough for short swims in summer, especially during calm weather, but swimmers are encouraged to stay close to the banks and remain cautious. For those preferring to stay dry, Richmond offers riverside walks, rowing, and boating, along with nearby attractions such as Richmond Park, the Royal Botanic Gardens at Kew, and beautiful Georgian riverside architecture.
