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

    Lagoinha 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.

    Lagoinha water temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 27th of February and are at their coldest on about the 13th of August, in the range 18 to 22°C (64 to 72°F). Year round warm water temperatures at Lagoinha climb to their maximum in the last days of February. Even then a rash vest and board shorts should be fine for surfing at any time of year. Lagoinha water temperatures are coldest in the third week of August. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.

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