*** 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
#County Durham
Blackton Reservoir in County Durham typically has cool water year-round, reflecting its upland setting. Seasonal surface temperatures commonly range from about 1–6 °C (34–43 °F) in winter, rising to roughly 6–12 °C (43–54 °F) in spring and autumn, and reaching around 14–18 °C (57–64 °F) in the warmest weeks of summer. These figures can vary with weather, depth and inflow, so conditions on any given day may be colder than expected, especially below the surface.
Swimming at Blackton Reservoir is not officially promoted and is often discouraged because reservoirs are working water bodies with safety risks such as cold shock, hidden currents and infrastructure related to water supply. Local rules and signage may prohibit entry into the water for public health and operational reasons, so visitors should check with the landowner or water company and follow posted guidance. The surrounding area offers plenty of alternatives, including country walks, upland moorland scenery and attractions associated with the North Pennines Area of Outstanding Natural Beauty, plus nearby waterfalls and village amenities for day visitors.
