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
Norwich, the historic city of Norfolk, is built around the River Wensum, a clear chalk stream that winds gently through its centre. The river’s water temperature remains cool throughout the year, influenced by underground springs and steady flow. In winter, it averages around 6–8 °C (43–46 °F), rising to about 9–11 °C (48–52 °F) in spring. During summer, the surface water can warm to 15–17 °C (59–63 °F) in sheltered areas, though shaded stretches through the city often stay several degrees cooler. By autumn, temperatures gradually fall again toward 10–12 °C (50–54 °F), maintaining the river’s clear and refreshing character year-round.
Swimming in the River Wensum around Norwich is permitted in certain places but should be done with care. The river flows through both rural and urban sections, and some areas are designated for wildlife conservation or navigation. Wild swimmers often prefer upstream stretches outside the city, where the water is cleaner and currents are gentle. Within Norwich, the river is better suited for kayaking, paddleboarding, and riverside walks. Wetsuits are recommended for longer swims due to the cool temperature. The city’s riverside paths connect to cultural landmarks such as Norwich Cathedral, Pull’s Ferry, and the scenic trails leading toward the Norfolk Broads.
