Stoney Point Water Temperature Graph

All of the graphs for the surf breaks presented on are on the same scale to enable comparison between locations around the world.

Stoney Point water temperatures peak in the range 14 to 18°C (57 to 64°F) on around the 15th of August and are at their minimum on about the 10th of February, in the range 3 to 5°C (37 to 41°F). The warmest seasonal water temperatures at Stoney Point in mid August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The minimum water temperatures at Stoney Point 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 in early to mid February.

Actual sea surface water temperatures close to shore at Stoney Point 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 Stoney Point.
