*** 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
#West Midlands (county)
Frankley Reservoir in the West Midlands follows a typical temperate pattern for shallow drinking-water impoundments. In winter surface temperatures commonly range from about 4–8 °C (39–46 °F), warming through spring to roughly 6–14 °C (43–57 °F). On warm summer days the top layers can reach around 15–22 °C (59–72 °F), while autumn cooling brings readings back to roughly 8–15 °C (46–59 °F). Deeper water remains significantly colder year-round, and variations in depth and weather mean surface temperatures can change quickly.
Swimming at Frankley Reservoir is generally not allowed, as the site forms part of the public water supply and restrictions are in place to protect water quality and public safety. Hazards such as cold-water shock, underwater obstacles and strong currents make unsupervised bathing risky, so casual wild swimming is discouraged. Instead visitors tend to enjoy the surrounding green spaces for walking, cycling and birdwatching, and can find local villages, cafés and country parks nearby that offer recreational alternatives without entering the reservoir.
