Water Temperature: Daily Trends, Historical Records, and Forecast

❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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

The Manchester, Bolton and Bury Reservoir sits in Greater Manchester with typically cool water year-round. Surface temperatures in winter usually fall to about 4–8 °C (39–46 °F), spring and autumn commonly see 6–14 °C (43–57 °F), while on warmer summer days the water may warm to roughly 14–22 °C (57–72 °F). These figures vary with depth, weather and recent rainfall, so cold layers can persist even in sunny months. The reservoir is fed by local rivers and managed partly for water supply, so open swimming is not universally permitted. Where swimming is allowed it tends to be in designated, supervised or organised wild-swim sessions; otherwise restrictions exist because of cold water shock risk, submerged hazards and water quality protection.

Access around the reservoir offers good walking and birdwatching, and it sits close to the West Pennine Moors and popular spots such as Rivington Pike, plus the towns of Bolton and Bury with their markets and museums. Anyone planning to swim should check local signage and permissions, use a buddy system, wear a buoyancy aid if unsure, and respect conservation and safety notices.
