We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

Prainha 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.

Prainha sea temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 27th of February and are at their minimum on about the 23rd of July, in the range 16 to 20°C (61 to 68°F). Year round warm sea temperatures at Prainha climb to their highest in the last days of February. Even then a rash vest and board shorts should be fine for surfing at any time of year. The minimum Prainha sea 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 Prainha 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 Prainha. Refer to our detailed weather forecasts for this information.
