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
Upper Roddlesworth Reservoir, set within the West Pennine Moors of Lancashire, stays cold for most of the year. Surface temperatures typically range from about 0–4 °C (32–39 °F) in winter, climb to roughly 4–10 °C (39–50 °F) in spring and autumn, and reach their highest in summer at around 12–18 °C (54–64 °F) on warm, still days. Because it is a relatively small upland impoundment, deeper water and lack of thermal mixing mean conditions remain chilly even in summer and can feel much colder once you leave the sun-warmed surface.
Swimming in Upper Roddlesworth is generally discouraged and in many cases not permitted: the reservoir is part of a water supply system and there are official safety and water-quality reasons for restricting bathing. Cold temperatures, hidden underwater obstacles and steep banks also present real hazards. Despite this, some experienced wild swimmers do visit unofficially, accepting the risks. The area is nevertheless popular for walking, birdwatching and reservoir-side trails, with nearby sights such as Rivington Pike and other Pennine moorland reservoirs offering accessible outdoor activities.
