Larsen Street 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.

Larsen Street sea water temperatures peak in the range 16 to 20°C (61 to 68°F) on around the 12th of February and are at their minimum on about the 20th of August, in the range 12 to 14°C (54 to 57°F). The highest Larsen Street sea water temperatures in the second week of February require something like a 3/2mm fully sealed wetsuit. The minimum sea water temperatures at Larsen Street in mid to late August 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 Larsen Street 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 Larsen Street.
