*** 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
#Somerset
Ashford Reservoir in Somerset typically has cool water year-round. Surface temperatures in winter usually sit around 4–7 °C (39–45 °F), rising through spring to roughly 8–13 °C (46–55 °F). In the warmest months the reservoir can reach about 15–22 °C (59–72 °F) on calm, sunny days, then fall back to roughly 10–14 °C (50–57 °F) in autumn. As with many reservoirs, deeper water and shaded areas remain noticeably colder than the surface, so actual conditions can vary with weather, wind and recent rainfall.
Swimming at Ashford Reservoir is generally not permitted because it is managed for water supply and safety reasons; reservoirs can contain hidden hazards, steep banks and low temperatures that create a risk of cold-water shock, and landowners often prohibit unsupervised bathing to protect water quality. Local authorities tend to direct swimmers to designated open-water sites. The area around the reservoir, however, offers pleasant countryside walking, birdwatching and traditional Somerset villages, with the Quantock Hills and Exmoor accessible nearby for broader outdoor exploration.
