*** 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
Warrington, a large town in Cheshire, is situated along the middle reaches of the River Mersey, where the water flows wide and steady before turning tidal farther downstream. The Mersey here reflects the mild maritime climate of northwest England, with gradual seasonal temperature changes. In winter, the river typically remains between 4 and 6°C (39–43°F), staying cold and fast-flowing. By spring, it warms slowly to around 8–10°C (46–50°F). During midsummer, especially in July and August, the water can reach 16–18°C (61–64°F) in calm, sunlit stretches, offering relatively comfortable conditions for outdoor recreation. As autumn arrives, the temperature cools again to about 10–12°C (50–54°F), keeping a steady freshness that lasts into late October.
Swimming in the River Mersey near Warrington is permitted but should be approached with caution. The water is generally clean enough for short dips, but the current can be unpredictable, particularly after rainfall. Experienced wild swimmers sometimes enjoy secluded areas during warm summer weather, while others prefer the safety of nearby open-water venues. For most residents, the Mersey is best appreciated through its riverside paths, parks, and bridges. Warrington’s location also provides easy access to Walton Hall Gardens, Sankey Valley Park, and the scenic Mersey Forest, which together offer peaceful green spaces along the river corridor.
