Today, many surfers would wear a spring wetsuit, a neoprene hood, gloves and boots.
The water temperature (15 °C) at Sky Williams is not too cold today but the windchill (4 °C) will make the air temperature seem much colder than the sea and it is forecast to be cloudy too so a chilly prospect. You'll need at least a hooded spring wetsuit to keep surf at Sky Williams today, maybe neoprene boots and gloves too.

Below is a graph of Historical Sea Surface Temperature for Sky Williams. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. 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.
Sky Williams water temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 8th of February and are at their lowest on about the 27th of August, in the range 12 to 14°C (54 to 57°F). The maximum Sky Williams water temperatures in early to mid February require something like a 3/2mm fully sealed wetsuit. The lowest water temperatures at Sky Williams in the last days of August 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 Sky Williams 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 Sky Williams.
