All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.
Kings Rock sea water temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 15th of August and are at their minimum on about the 1st of March, in the range 13 to 14°C (55 to 57°F). The maximum Kings Rock sea water temperatures in mid August require something like a 3/2mm fully sealed wetsuit. The minimum sea water temperatures at Kings Rock at the beginning of March are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days.
Actual sea surface water temperatures close to shore at Kings Rock can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at Kings Rock.
