Today, many surfers would wear a spring wetsuit.
Sunny with very warm air temperatures, feeling like 25 °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.
Slufter water temperatures peak in the range 16 to 20°C (61 to 68°F) on around the 17th of August and are at their minimum on about the 23rd of February, in the range 3 to 8°C (37 to 46°F). The highest Slufter water temperatures in the middle of August require something like a 3/2mm fully sealed wetsuit. The minimum water temperatures at Slufter mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here in the fourth week of February.
Actual sea surface water temperatures close to shore at Slufter 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 Slufter.
