    Sonho 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.

    Sonho water 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 26th of July, in the range 17 to 21°C (63 to 70°F). Year round warm water temperatures at Sonho climb to their warmest 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 Sonho 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 Sonho 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 Sonho.
