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.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Average Monthly Water Temperature
Annual Water Temperature Trend
Weymouth sits on the sheltered southern coast of England, backing onto a broad sandy bay and forming part of Dorset’s coastline. The sea here is influenced by the relatively mild maritime climate of the English Channel, so water temperatures are cooler than summer air temperatures but milder than many northern coasts. Typical seasonal sea temperatures around Weymouth range from about 6–8 °C in winter, rising to roughly 8–12 °C in spring. In summer the water commonly warms to around 15–19 °C, with the warmest weeks occasionally approaching 20 °C during heatwaves. Autumn sees a gradual cooling, with temperatures generally falling to around 11–15 °C. Local conditions such as wind, tides and spring-summer sunshine mean daily values can vary, and sheltered parts of the bay warm slightly sooner than exposed headlands.

Swimming Conditions
The bay’s gentle gradient and wide expanse of sand make Weymouth a popular beach holiday destination for family swimming and paddling. During the main season there is seasonal lifeguard cover on key stretches of beach and facilities such as a promenade, showers and cafes, which support day visitors and water-sport users. Open-water swimmers, clubs and people using kayaks, paddleboards or wetsuits find plenty of access points, but should be aware of tidal flows and changeable weather; a wetsuit is commonly used outside the warmest weeks when water is below about 15 °C. Outside peak summer the town is quieter, offering brisker sea swims and scenic coastal routes for those seeking a more active beach break.
