All of the graphs for the surf breaks presented on are on the same scale to enable comparison between locations around the world.

El Estero sea temperatures peak in the range 28 to 30°C (82 to 86°F) on around the 14th of May and are at their coldest on about the 4th of February, in the range 25 to 29°C (77 to 84°F). Year round warm sea temperatures at El Estero 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 El Estero 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 El Estero.
