Water Temperature: Daily Trends, Historical Records, and Forecast

❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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

#Greater Manchester

Greenbooth Reservoir, on the moorland edge of Greater Manchester, typically has cool water year-round. In winter months water temperatures commonly sit around 4–8 °C (39–46 °F). Spring sees a slow rise to roughly 6–12 °C (43–54 °F), while summer brings the warmest conditions, often 14–20 °C (57–68 °F) and occasionally touching about 22 °C (72 °F) on very warm days. In autumn temperatures fall back to around 8–14 °C (46–57 °F). These figures are approximate and vary with weather, depth and wind.

Swimming at Greenbooth is generally not officially permitted: it is part of the local water supply and open water carries risks such as cold shock, hidden currents and water quality concerns, so landowners and water companies discourage regular bathing. That said, some experienced wild swimmers do visit at their own risk. The reservoir is nevertheless popular for walking and birdwatching, with nearby attractions including Pennine moorland scenery, local trails and other regional reservoirs and country parks suitable for more organised recreation.
