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.

Big Wave Bay sea temperatures peak in the range 27 to 30°C (81 to 86°F) on around the 11th of July and are at their coldest on about the 17th of January, in the range 18 to 22°C (64 to 72°F). Year round warm sea temperatures at Big Wave Bay climb to their warmest in the second week of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. Big Wave Bay sea temperatures are coldest in the middle of January. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.

Actual sea surface water temperatures close to shore at Big Wave Bay 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 Big Wave Bay.
