*** 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
#Derbyshire
Bottoms Reservoir in Derbyshire typically has cool waters year-round because of its upland location. Surface temperatures in winter often range from about 1–6 °C (34–43 °F), spring warms to roughly 5–12 °C (41–54 °F), summer peak temperatures are commonly around 12–18 °C (54–64 °F), and autumn usually sees a decline back to roughly 8–12 °C (46–54 °F). These figures can vary with weather, depth and wind; deeper water and cloudy periods keep temperatures lower than shallow lakes.
Swimming at Bottoms Reservoir is generally not officially sanctioned and is often discouraged for safety and water-quality reasons. Reservoirs can be deep, cold and have hidden currents or infrastructure, and many are managed as part of drinking-water systems, leading to access restrictions and warning signage. Visitors tend to enjoy the immediate surroundings on foot instead; nearby attractions include Peak District walking routes, limestone dales and scenic villages, offering plentiful opportunities for hiking, birdwatching and photography rather than open-water recreation. Always check local notices before attempting to enter any reservoir.
