Costa Nova water temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 20th of August and are at their lowest on about the 2nd of March, in the range 13 to 15°C (55 to 59°F). The maximum Costa Nova water temperatures in mid to late August require something like a 3/2mm fully sealed wetsuit. The lowest water temperatures at Costa Nova in early March are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days.
Actual sea surface water temperatures close to shore at Costa Nova 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 Costa Nova.
