Thames

Sea area of the Met Office Shipping Forecast. Covers waters off southeast England, centered on the Thames Estuary.

From the River Thames (“Tamesis,” “dark river”), Thames is relatively sheltered, with southwest winds of Force 3–5 and moderate seas, but vulnerable to severe storm surges. The 1928 Thames flood, following a storm surge, caused over 300 fatalities and reshaped London’s flood mitigation.
