    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.

    Banzai sea temperatures peak in the range 22 to 25°C (72 to 77°F) on around the 5th of February and are at their coldest on about the 21st of August, in the range 17 to 20°C (63 to 68°F). Banzai sea temperatures are always warm reach their maximum at the beginning of February. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The coldest Banzai sea temperatures in mid to late August require something like a 3/2mm fully sealed wetsuit.

    Actual sea surface water temperatures close to shore at Banzai 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 Banzai.
