*** 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
#Northamptonshire
Welford Reservoir, on the edge of Northamptonshire, has water that varies markedly through the year. Surface temperatures typically lie around 6–15 °C (43–59 °F) in spring, rise to about 15–22 °C (59–72 °F) in summer, cool to roughly 8–15 °C (46–59 °F) in autumn and fall to near 1–6 °C (34–43 °F) in winter. Deeper water stays colder year-round, so anyone considering time in the water should expect a sharp chill below the surface even on warm days.
Swimming at Welford Reservoir is generally discouraged and in many areas not permitted due to safety, hidden hazards and the site’s management for wildlife and water-related uses. The shoreline and paths are popular for walking, and the reservoir draws anglers and birdwatchers rather than casual bathers. Nearby attractions include the pretty village of Welford with its pubs and footpaths, the rolling Northamptonshire countryside for cycling and hiking, and Market Harborough a short drive away for shops and eateries, making the area appealing for day visits even if open-water swimming isn’t recommended.
