We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
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.
Main Beach sea water temperatures peak in the range 28 to 29°C (82 to 84°F) on around the 24th of July and are at their coldest on about the 11th of February, in the range 17 to 22°C (63 to 72°F). Year round warm sea water temperatures at Main Beach climb to their maximum in the fourth week of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. The coldest Main Beach sea water temperatures in the second week of February require something like a 3/2mm fully sealed wetsuit.
Actual sea surface water temperatures close to shore at Main Beach 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 Main Beach.
