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

Ocos water temperatures peak in the range 29 to 30°C (84 to 86°F) on around the 14th of May and are at their lowest on about the 15th of January, in the range 25 to 28°C (77 to 82°F). Year round warm water temperatures at Ocos mean that a rash vest and board shorts should be fine for surfing at any time of year

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