*** 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
Rochester, with its stunning Norman castle and cathedral, is situated on the River Medway as it widens into its tidal reaches. Consequently, the river's water temperature varies widely with the seasons, heavily influenced by the cooler coastal conditions of the Thames Estuary nearby. River temperatures typically range from a cold low of around 6∘C (43∘F) in the winter months of January and February, to a mild high of approximately 18∘C (64∘F) in late summer, particularly in August and September.
Swimming in this section of the River Medway is strongly discouraged and generally not permitted due to major hazards. The river here is a busy, tidal working waterway with commercial shipping traffic, powerful currents, and the presence of hidden underwater debris. For safe and designated swimming, locals often use The Strand Lido, a unique riverside tidal saltwater pool in nearby Gillingham. Rochester’s other major attractions center on its rich history, including the imposing Rochester Castle, the magnificent Rochester Cathedral, and the Historic Dockyard Chatham just a short distance away.
