Annual Water Temperature Trend

Sheerness sits on the north coast of the Isle of Sheppey in Kent, fronting the Thames Estuary and the North Sea. The estuarine location and tidal influence mean sea temperatures are modest by southern European standards and follow a typical British coastal pattern. Winter surface temperatures commonly range around 6–8 °C, with early spring gradually warming to roughly 8–12 °C. The warmest months are July and August when surface temperatures usually reach about 16–19 °C, occasionally 20 °C in very warm summers. Through autumn the water cools back to roughly 12–15 °C by October and continues downward towards winter values. Local conditions such as wind, tides and freshwater runoff can cause short-term variation from these averages.
