Today, many surfers would wear a spring wetsuit.
Sunny with very warm air temperatures, feeling like 26 °C once we account for air movement. In contrast the sea remains relatively cold (18 °C). Surfers should wear a spring or summer wetsuit though no doubt some would wear less neoprene on such a warm day, no matter what temperature the sea is.

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.
Costa da Caparica sea water temperatures peak in the range 20 to 22°C (68 to 72°F) on around the 16th of August and are at their lowest on about the 24th of February, in the range 14 to 16°C (57 to 61°F). Costa da Caparica sea 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 lowest sea water temperatures at Costa da Caparica in the fourth week of February 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 da Caparica 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 da Caparica.
