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

Caldeirao 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.

Caldeirao water temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 7th of March and are at their minimum on about the 13th of August, in the range 17 to 20°C (63 to 68°F). Year round warm water temperatures at Caldeirao climb to their warmest in the first part of March. Even then a rash vest and board shorts should be fine for surfing at any time of year. The minimum Caldeirao water temperatures in the third week of August require something like a 3/2mm fully sealed wetsuit.

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