*** 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
Derby, a vibrant city in the East Midlands, stands on the River Derwent, where the water flows gently through parks and historic industrial sites. The river here reflects the region’s temperate climate, with moderate seasonal changes in water temperature. During winter, the Derwent typically stays around 3–5°C (37–41°F), remaining cold and fast-flowing after rainfall. By spring, it gradually warms to about 8–11°C (46–52°F). In midsummer, during July and August, the river can reach 15–18°C (59–64°F), especially in slower, sunlit sections. As autumn returns, the temperature cools again to around 10–12°C (50–54°F), keeping a refreshing but comfortable character that lasts into late October.
Swimming in the River Derwent at Derby is possible, though it is best suited for experienced open-water swimmers. Within the city, the river has variable depths and currents, so most people prefer calmer stretches upstream or in nearby countryside locations. The water quality is generally good, and summer conditions can be pleasant for short swims or paddling. Many residents instead enjoy the riverbanks through walking, cycling, or kayaking. Derby’s riverside setting connects easily to wider attractions such as Darley Park, the Derwent Valley Mills World Heritage Site, and the rolling landscapes of the nearby Peak District.
