*** 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

#Leigh, Greater Manchester

Pennington Flash is a shallow inland reservoir and country park near Leigh in Greater Manchester. Water temperatures vary with the seasons: in winter the surface commonly sits around 4–8 °C (39–46 °F), spring warms to roughly 6–14 °C (43–57 °F), summer can reach about 14–20 °C (57–68 °F), and autumn typically drops back toward 8–14 °C (46–57 °F). Because the flash is exposed and relatively shallow, temperatures can change quickly with weather and wind, and algae or runoff can affect water quality after heavy rain.

There is no designated, lifeguarded bathing area at Pennington Flash and swimming is generally not officially encouraged for safety reasons — boat and sailing traffic, hidden underwater hazards and variable water quality present risks. Nevertheless, organised watersports such as sailing and windsurfing take place, and some experienced wild swimmers visit at their own risk. The surrounding country park offers birdwatching, walking and cycling routes, a visitor area and play spaces, while nearby towns such as Leigh and Haigh Country Park provide additional attractions.
