*** 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
#North Yorkshire
Scar House Reservoir, high in Nidderdale, typically has cold water throughout the year. Surface temperatures commonly range by season: winter about 1–6 °C (34–43 °F), spring 4–10 °C (39–50 °F), summer 10–18 °C (50–64 °F) on the warmest days, and autumn 6–12 °C (43–54 °F). Deeper water remains colder than the surface and short spells of warm weather can raise only the upper layers. Wind, rainfall and reservoir release patterns also produce frequent short-term variations in temperature.
Swimming at Scar House is generally not permitted and is discouraged for safety and water-quality reasons. The reservoir forms part of the local drinking-water system and is managed to protect supplies; steep banks, sudden depth changes, cold water shock and lack of lifeguards add real hazards. Visitors who want to swim should follow signage, use formal facilities or organised open-water events elsewhere. The area still rewards walkers and nature lovers, with scenic routes around Scar House and neighbouring Angram Reservoir, upland moors within the Nidderdale Area of Outstanding Natural Beauty, and the nearby market town of Pateley Bridge.
