Today, many surfers would wear a rashvest wetsuit.
Sunny with very warm air temperatures, feeling like 28 °C once we account for any wind. Sea temperatures (21 °C) warm too. Staying warm in the water won't be a problem in board-shorts, but wear at least a rash-vest to keep the UV off.

Below is a graph of Historical Sea Surface Temperature for Mesa. 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.
Mesa water temperatures peak in the range 16 to 19°C (61 to 66°F) on around the 5th of September and are at their coldest on about the 27th of March, in the range 12 to 15°C (54 to 59°F). The warmest seasonal water temperatures at Mesa at the beginning of September lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The coldest water temperatures at Mesa in the last days of 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 Mesa 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 Mesa.
