Below is a graph of Historical Sea Surface Temperature for Avalanche. 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.

Avalanche water temperatures peak in the range 13 to 18°C (55 to 64°F) on around the 24th of August and are at their lowest on about the 28th of January, in the range 8 to 11°C (46 to 52°F). The warmest seasonal water temperatures at Avalanche in the fourth week of August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. At its lowest in the fourth week of January, low water temperatures at Avalanche are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

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