We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

Stony 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.

StonyPoint sea temperatures peak in the range 15 to 18°C (59 to 64°F) on around the 19th of August and are at their lowest on about the 5th of February, in the range 4 to 6°C (39 to 43°F). The highest seasonal sea temperatures at StonyPoint in the third week of August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The lowest sea temperatures at StonyPoint 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 February.

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