*** 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
Leigh Reservoir in Somerset typically has cool water year-round. In winter surface temperatures often fall to about 4–8 °C (39–46 °F), warming through spring to roughly 8–14 °C (46–57 °F). Peak summer temperatures are usually between 15–22 °C (59–72 °F), while autumn sees a gradual decline to around 10–16 °C (50–61 °F). Deeper water remains colder than surface readings, and sudden changes in weather or inflows can lower temperatures quickly, so these ranges are indicative rather than precise.
Swimming at Leigh Reservoir is generally discouraged or restricted because many reservoirs supply drinking water and have safety and water-quality considerations; signage or local bylaws often prohibit wild swimming, and there are no lifeguards. Where locals do swim, it is at their own risk and requires caution for cold shock, submerged hazards and variable banks. Nearby attractions include the Mendip Hills and Cheddar Gorge for walking and sightseeing, along with quiet rural villages and birdwatching opportunities that make the area attractive to visitors.
