*** 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
#Devon
Slade Reservoir’s water temperatures follow the typical pattern for small upland reservoirs in Devon. Surface temperatures in winter usually sit between about 4–8 °C (39–46 °F), rising in spring to roughly 6–12 °C (43–54 °F) as daylight increases. In summer the surface can warm to around 14–20 °C (57–68 °F) on sunnier days, though deeper water remains much colder. By autumn temperatures generally fall back to 8–13 °C (46–55 °F). These are approximate seasonal ranges; local weather, depth and inflows all influence actual readings and conditions can change quickly.
Swimming at Slade Reservoir is generally discouraged or restricted because reservoirs often function as part of the public water supply and present hidden hazards such as cold deep water, steep banks and submerged structures. Where open-water swimming is permitted, it tends to be in supervised, organised events or designated areas only. Visitors to the area can still enjoy nearby attractions such as riverside and woodland walks, birdwatching, and coastal paths and beaches a short drive away, offering opportunities for picnics, photography and gentle exploration of Devon’s countryside.
