Below is a graph of Historical Sea Surface Temperature for Boneyards. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

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.

Boneyards water temperatures peak in the range 22 to 25°C (72 to 77°F) on around the 2nd of February and are at their coldest on about the 5th of August, in the range 18 to 20°C (64 to 68°F). Boneyards water temperatures are always warm reach their warmest in early February. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The coldest Boneyards water temperatures at the beginning of August require something like a 3/2mm fully sealed wetsuit.

Actual sea surface water temperatures close to shore at Boneyards 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 Boneyards.
