*** 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
#Wiltshire
Wilton Water is a small reservoir in Wiltshire whose surface temperatures follow the local seasonal cycle. In winter the water typically sits around 3–6 °C (37–43 °F), rising through spring to roughly 6–14 °C (43–57 °F). Peak summer temperatures often reach 15–22 °C (59–72 °F), occasionally higher during heatwaves, while autumn sees a gradual fall back to about 8–15 °C (46–59 °F). Because it is relatively shallow and exposed, air temperature and sunlight cause noticeable day-to-day variation in surface warmth.
Swimming at Wilton Water is not a formal, managed activity; there is no designated bathing area, lifeguards, or facilities, and access can be limited because the site functions as a reservoir and nature-rich habitat. For safety, water quality and conservation reasons local authorities and landowners generally discourage open swimming. Visitors looking for recreation will find other nearby options: the historic town of Wilton with Wilton House, the city of Salisbury and its cathedral, and numerous walking routes across the surrounding downs and nature reserves.
