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
Bath, a historic city in Somerset, is built along the River Avon, where the water flows calmly through the surrounding hills before continuing toward Bristol. The river’s temperature reflects the mild climate of southwest England, changing gradually with the seasons. In winter, the Avon near Bath typically remains between 4 and 6°C (39–43°F), staying cold and clear. By spring, it begins to warm to around 9–12°C (48–54°F). During midsummer—particularly in July and August—the water can reach 17–20°C (63–68°F), with sheltered sections near the city becoming pleasantly warm on sunny days. In early autumn, the river cools again to about 12–14°C (54–57°F), maintaining a refreshing feel that lasts into October.
Swimming in the River Avon at Bath is allowed in certain stretches but requires care, as the current can vary and the waterway also serves small boats. The river’s cleaner and calmer sections upstream or downstream of the city are occasionally used by wild swimmers during warm months. Many locals prefer paddleboarding, kayaking, or riverside walks to enjoy the scenery. Bath’s riverside setting complements its wider attractions, including the Roman Baths, Pulteney Bridge, and the elegant Georgian architecture that gives the city its timeless character along the flowing Avon.
