⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. 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
Cambridge, in eastern England, is a city closely associated with the River Cam, which flows through its historic centre and along college lawns. The river’s water temperature changes gently with the seasons, reflecting the region’s mild and relatively dry climate. In winter, the water typically averages around 4–6 °C (39–43 °F), while in spring it rises to about 8–10 °C (46–50 °F). During the summer, surface temperatures can reach 16–18 °C (61–64 °F) in calm, sunlit areas, though shaded sections and deeper channels remain cooler. By autumn, the river cools again toward 10–12 °C (50–54 °F), maintaining a fresh and moderate temperature throughout the year.
Swimming in the River Cam is permitted in certain stretches and has long been a local tradition, especially during the warmer months. The water quality is generally good, though swimmers are advised to stay clear of boat traffic and strong currents near locks. Many people swim in designated or quiet spots upstream from the city centre, where the river is clean and accessible. Wetsuits are common outside midsummer for comfort. Beyond swimming, Cambridge’s riverside paths, punting activities, and historic colleges create a distinctive atmosphere. Nearby attractions include Grantchester Meadows, Jesus Green Lido, and the city’s renowned museums and gardens.
