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
Tewkesbury, a historic town in Gloucestershire, sits where the River Severn meets the River Avon, creating a distinctive landscape of slow-moving water and wide floodplains. The Severn in this area reflects the mild climate of southwest England, with average winter water temperatures of around 5–7°C (41–45°F). As spring arrives, the river gradually warms to 10–13°C (50–55°F), reaching its peak in July and August, when temperatures typically range from 17 to 20°C (63–68°F). By early autumn, the water begins to cool again, settling between 12 and 14°C (54–57°F). Even in summer, the Severn’s flow and depth keep it cooler than nearby lakes or canals, offering refreshing but brisk conditions for anyone entering the water.
Swimming in the River Severn at Tewkesbury is possible but approached with caution. The river’s currents, weirs, and boat traffic make it better suited to experienced wild swimmers who understand local conditions. More commonly, residents and visitors enjoy kayaking or paddleboarding along the quieter backwaters, particularly near the confluence with the Avon. For those preferring to stay dry, Tewkesbury offers scenic riverside walks, historic architecture, and landmarks such as Tewkesbury Abbey, all set against the tranquil backdrop of England’s longest river.
