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

#Lancashire

Belmont Reservoir on the West Pennine Moors tends to be cold for much of the year. Typical surface temperatures range from around 1–6 °C (34–43 °F) in winter, rising to roughly 4–12 °C (39–54 °F) in spring. In summer the shallowest, sun-warmed areas may reach 12–20 °C (54–68 °F) on warmer days, while autumn sees a gradual cooling back to about 8–14 °C (46–57 °F). These figures can vary with recent weather, wind and the reservoir’s depth, and the deeper water remains significantly colder than the surface.

Swimming in Belmont Reservoir is not officially permitted: the site functions as part of the local water supply and public safety authorities discourage bathing because of cold water shock, hidden currents and underwater hazards. Despite occasional wild swimmers, authorities advise against entering the water. The area is still popular for walking and birdwatching, with nearby attractions including Rivington Pike and its terraced gardens, the West Pennine Moors’ hiking routes, and views towards Winter Hill and Darwen Tower, all offering reasons to visit even without taking a dip.
