    Sunny with very warm air temperatures, feeling like 25 °C once we account for any wind. Sea temperatures (21 °C) warm too. Staying warm in the water won't be a problem in board-shorts, but wear at least a rash-vest to keep the UV off.

The Jetty sea water temperatures are always warm reach their maximum in early to mid August. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The coldest sea water temperatures at The Jetty mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here at the beginning of March.

    Actual sea surface water temperatures close to shore at The Jetty 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 The Jetty.
