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 (19 °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.

Below is a graph of Historical Sea Surface Temperature for Long Beach. 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.
Long Beach water temperatures peak in the range 27 to 29°C (81 to 84°F) on around the 18th of July and are at their minimum on about the 1st of February, in the range 18 to 23°C (64 to 73°F). Year round warm water temperatures at Long Beach climb to their maximum in the third week of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. Long Beach water temperatures are minimum at the beginning of February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.
Actual sea surface water temperatures close to shore at Long Beach 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 Long Beach.
