*** 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 River Severn at Gloucester, a city famed for its historic docks and cathedral, experiences significant temperature variations throughout the year. During the summer months, water temperatures typically rise to between 17 and 20∘C (63 and 68∘F), offering the warmest conditions. However, the Severn can be extremely cold in winter, with temperatures dropping substantially, often settling in the range of 6 to 9∘C (43 to 48∘F).
Direct swimming in the River Severn near Gloucester is generally discouraged and is done entirely at one's own risk, as the river here is deep, often fast-flowing, and subject to significant tidal influence, particularly further downstream. Hazards also include commercial boat traffic in the docks and potential water quality issues. For safer, organised open-water swimming, local facilities such as dedicated lakes or lidos are recommended. Beyond the river, the city offers attractions like the stunning Gloucester Cathedral, the vibrant Gloucester Docks area with its museums and retail outlets, and the nearby rolling hills of the Cotswolds.
