*** 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
#Yorkshire
Fewston Reservoir in the Washburn Valley stays noticeably cool through the year. Typical surface temperatures range from about 2–6 °C (36–43 °F) in winter, 6–12 °C (43–54 °F) in spring, and roughly 12–18 °C (54–64 °F) in summer on warmer days, falling back to around 6–12 °C (43–54 °F) in autumn. Wind, depth and shading from the valley mean the water can feel several degrees colder than air temperatures, and thermal stratification can produce colder layers below the surface.
Swimming is generally not recommended at Fewston. The reservoir is part of the public water supply and the landowner and water company advise against open-water bathing because of cold water shock, underwater hazards, and potential impacts on water quality; some locations also carry signage restricting access. Visitors instead use waymarked walks around Fewston and neighbouring Swinsty Reservoir, enjoy birdwatching in the Washburn Valley, or travel a short distance to Harrogate for townsfolk amenities and formal swimming facilities.
