We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
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.
Cogumelo water temperatures peak in the range 20 to 23°C (68 to 73°F) on around the 16th of August and are at their coldest on about the 19th of February, in the range 15 to 17°C (59 to 63°F). Cogumelo water temperatures are maximum in the middle of August. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The coldest seasonal water temperatures at Cogumelo in the third week of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots.
Actual sea surface water temperatures close to shore at Cogumelo 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 Cogumelo.
