*** 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
#South Yorkshire
Agden Reservoir, high on the moorland of South Yorkshire, tends to be cool year-round. Typical surface temperatures in winter (December–February) are around 1–6 °C (34–43 °F). In spring (March–May) waters usually warm to roughly 4–12 °C (39–54 °F). Summer (June–August) surface readings commonly reach 10–18 °C (50–64 °F), though brief warm spells can push parts of the reservoir toward 20 °C (68 °F). During autumn (September–November) temperatures typically fall back to about 6–12 °C (43–54 °F). Actual temperatures vary with weather, depth and time of day; deeper water stays colder than the surface.
Swimming at Agden is not officially promoted and can be restricted because the reservoir supplies water and has inherent safety risks—cold, deep water, hidden currents and underwater hazards. Wild swimmers sometimes visit, but local rules and signage should be checked and caution exercised; using a wetsuit, swim buoy and a companion is strongly advised. The area is popular for walking and birdwatching, with moorland scenery and nearby reservoirs and villages offering pleasant routes and country pubs for visitors.
