Backdoor Water Temperature Graph

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.

Backdoor sea water temperatures peak in the range 20 to 22°C (68 to 72°F) on around the 18th of August and are at their lowest on about the 21st of February, in the range 14 to 16°C (57 to 61°F). Backdoor sea water temperatures are highest in the third week of August. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The lowest sea water temperatures at Backdoor in mid to late February 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 Backdoor 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 Backdoor.
