*** 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)
Olton Reservoir in the West Midlands typically feels cool for much of the year. Seasonal surface temperatures often range from about 6–12 °C (43–54 °F) in spring, 15–22 °C (59–72 °F) in summer, 10–15 °C (50–59 °F) in autumn and 4–8 °C (39–46 °F) in winter. As with many small inland reservoirs, actual temperatures vary with weather, depth and sunshine, and sudden cold layers can persist even on warm days.
Swimming at Olton Reservoir is generally not permitted or is discouraged because of safety and environmental concerns: there are no lifeguards, underwater hazards and variable water quality, and the site is managed for wildlife and local water systems. For recreational swimming people usually use organised lidos, pools or designated open-water venues nearby. The reservoir sits close to Solihull town centre and green spaces such as Brueton Park and Tudor Grange, and the area is popular for walking, birdwatching and canal-side cycling rather than casual bathing.
