*** 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

Rumworth Lodge Reservoir, on the outskirts of Bolton in Greater Manchester, typically has cool water throughout the year. Surface temperatures commonly range from about 4–8 °C (39–46 °F) in mid-winter, rising to roughly 14–20 °C (57–68 °F) in late summer; spring and autumn sit between these extremes, around 8–14 °C (46–57 °F). Even in warm months, deeper water and shaded areas often remain significantly colder, and conditions can change quickly with weather, inflows and depth.

Open-water swimming at Rumworth Lodge Reservoir is generally discouraged and in many reservoirs effectively prohibited because of safety risks, water quality concerns and the operational needs of water supply infrastructure. There are no official swimming areas or lifeguards, so anyone thinking of entering the water should check local signage and guidance from the water company or council. Cold-water shock and submerged hazards make unplanned immersion hazardous; anyone contemplating swimming should take appropriate precautions and seek permission where required. For alternative recreation, Bolton town centre, historic Smithills Hall and the nearby Rivington Country Park with its hill walks and other reservoirs offer accessible attractions.
