Trespassers sea temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 1st of March and are at their coldest on about the 2nd of September, in the range 14 to 15°C (57 to 59°F). The warmest Trespassers sea temperatures at the beginning of March require something like a 3/2mm fully sealed wetsuit. The coldest sea temperatures at Trespassers in early September 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 Trespassers 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 Trespassers.
