About this reading

The value comes from the satellite analysis grid cell centred at 52.33° N, 1.69° E, under 1 km from the GeoNames point for Southwold. Each cell is about 1 km across. It is the nearest cell the analysis treats as open sea.

Please note. These are satellite-based estimates of the sea surface temperature on a grid about 1 km wide. Water at the shoreline, in rock pools, estuaries and shallow bays can be several degrees warmer or colder. Readings are usually one to two days old. This is not safety advice: check local lifeguard and coastguard guidance before swimming. Water below about 15 °C can cause cold water shock.
