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

Avana 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.

Avana sea temperatures peak in the range 27 to 28°C (81 to 82°F) on around the 1st of March and are at their lowest on about the 19th of August, in the range 22 to 24°C (72 to 75°F). Year round warm sea temperatures at Avana climb to their highest at the beginning of March. Even then a rash vest and board shorts should be fine for surfing at any time of year. Avana sea temperatures are always warm but dip to their lowest in the third week of August. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy.

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