*** 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
#Greater Manchester
Norman Hill Reservoir, in Greater Manchester, tends to be cool year-round. Typical surface temperatures run about 4–6 °C (39–43 °F) in winter, rise to roughly 6–14 °C (43–57 °F) through spring and autumn, and reach perhaps 14–18 °C (57–64 °F) in the warmest summer weeks. These figures can vary with weather, depth and inflow: shallow edges warm more quickly while deeper water and shaded areas remain cold. Sudden drops in temperature after rain or cold nights are common, so swimmers should expect brisk conditions outside a brief high-summer window.
Swimming at Norman Hill is generally not permitted for safety and supply reasons. Many reservoirs in the region are managed as drinking-water sources or have steep banks, hidden underwater hazards and strong undercurrents; signage and local bylaws normally prohibit wild swimming to reduce risk. Visitors instead use the site for walking and birdwatching; nearby attractions include moorland and valley trails of the Pennine fringe, local village amenities and other water bodies popular with permitted water-sports clubs. Always check on-site notices or local authority guidance before entering reservoir areas.
