*** 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
#Cumbria
Ullswater’s water is typically cold year-round. Surface temperatures in summer usually range from about 12–18 °C (54–64 °F) on warmer days, while spring and autumn generally see 6–12 °C (43–54 °F). In winter temperatures can fall to around 2–6 °C (36–43 °F). Swimming in Ullswater is allowed in many places because it is a public lake, but there are no widespread lifeguards and conditions can be changeable. Cold water shock, underwater hazards, strong wind-driven currents and steep banks make caution essential. Many people enjoy short swims or wild-swimming sessions, ideally with a partner, buoyancy aid, or wetsuit, and by following local signs and advice from waterside operators.
Nearby attractions add to the visit: the Aira Force waterfall, the Ullswater Steamers and the small villages of Glenridding and Pooley Bridge provide access and services, while the Lake District’s fells such as Helvellyn offer hiking and viewpoints. The Ullswater Way circuit gives a varied route around the lake for walkers.
