*** 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
#Lincolnshire
Covenham Reservoir, near Louth in Lincolnshire, is a cool, open-water body whose temperatures vary with the seasons. In winter the surface commonly falls to around 2–6 °C (36–43 °F), spring brings 6–12 °C (43–54 °F), summer can warm it to roughly 15–22 °C (59–72 °F), and autumn typically sits between 8–14 °C (46–57 °F). Even in summer the water can feel chilly and layered thermal differences and sudden drop-offs make conditions changeable.
Swimming at Covenham is not generally encouraged; the reservoir forms part of local water-supply infrastructure and access is managed for safety and water-quality reasons. Signs and landowners typically advise against wild swimming because of cold-water shock, unseen hazards and the need to protect potable water sources. Visitors looking to swim locally usually use supervised lidos, leisure centres or coastal beaches. The area remains attractive for other pursuits: walking and birdwatching around the shoreline, exploring the Lincolnshire Wolds, and visiting the nearby market town of Louth and its coastal resorts.
