Guaratuba Water Temperature Graph

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.

Guaratuba sea water temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 26th of February and are at their minimum on about the 24th of July, in the range 16 to 20°C (61 to 68°F). Year round warm sea water temperatures at Guaratuba climb to their highest in the fourth week of February. Even then a rash vest and board shorts should be fine for surfing at any time of year. The minimum Guaratuba sea water temperatures in the fourth week of July require something like a 3/2mm fully sealed wetsuit.

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