*** 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
Reading, a lively town in Berkshire, sits along one of the most attractive middle stretches of the River Thames. The river here flows at a moderate pace, surrounded by wooded banks and meadows that make it a popular spot for boating and riverside walks. Water temperatures in this area vary with the seasons but remain relatively mild for England. In winter, the Thames around Reading averages 5–7°C (41–45°F), staying cold and brisk. By spring, the water gradually warms to 10–13°C (50–55°F), and during the height of summer — July and August — temperatures often reach 18–21°C (64–70°F). In early autumn, the river cools back to around 13–15°C (55–59°F), maintaining a pleasant but refreshing feel.
Swimming in the River Thames at Reading is generally allowed, though it is best suited for confident swimmers who understand open-water conditions. The water quality is usually good, but care must be taken near locks and weirs where currents are stronger. Many residents enjoy wild swimming in quieter sections, especially around Mapledurham and Sonning, where the flow is gentle. For those who prefer to stay dry, the riverside paths, kayaking routes, and the town’s cultural attractions — including Reading Abbey ruins and Forbury Gardens — offer plenty of ways to enjoy the river’s peaceful setting.
