*** 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
#Greater London
Banbury Reservoir in Greater London, England is a shallow municipal reservoir whose surface temperatures follow the typical seasonal pattern for urban reservoirs in the region. In winter the water often sits around 4–7 °C (39–45 °F), rising in spring to roughly 6–12 °C (43–54 °F). Summer surface temperatures commonly reach 15–22 °C (59–72 °F), and in warm spells can approach the mid-20s °C (mid-70s °F), while autumn sees cooling back to about 10–14 °C (50–57 °F). These figures are approximate averages for surface layers; deeper water and shaded areas remain colder year-round and temperatures can vary with weather, inflows and reservoir management.
Swimming at Banbury Reservoir is generally not permitted. The site functions as part of the water supply and conservation infrastructure, and access is restricted for safety, water quality and operational reasons; cold-water shock, underwater hazards and water treatment requirements are additional concerns. Visitors seeking recreation will find nearby attractions such as the Walthamstow Wetlands nature reserve with birdwatching and walking routes, the William Morris Gallery in Walthamstow and the Lea Valley linear park with cycling and riverside paths.
