Year round warm sea temperatures at Silveira climb to their maximum 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 coldest Silveira sea 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 Silveira 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 Silveira.
