Praia Grande sea temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 28th of February and are at their minimum on about the 25th of July, in the range 16 to 20°C (61 to 68°F).

The minimum Praia Grande sea temperatures in late July require something like a 3/2mm fully sealed wetsuit.
Actual sea surface water temperatures close to shore at Praia Grande 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 Praia Grande.
