Zero Water Temperature and Wetsuit Guide

(Los Angeles County, USA)

Today's Zero sea temperature is 18.8 °C.

Statistics for 21 Sep (1981–2005) – mean: 18.0 °C, range: 16.5 °C to 20.3 °C

Sunny with pleasantly warm air temperatures (feeling like 21 °C once we account for wind), yet at 18 °C the sea remains several degrees colder than the air at Zero. The majority of surfers will need a spring wetsuit though a summer suit or even a shorty may suffice for a short session.

Below is a graph of Historical Sea Surface Temperature for Zero. 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.

Zero Water Temperature Graph

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.

Zero sea temperatures peak in the range 16 to 20°C (61 to 68°F) on around the 5th of September and are at their minimum on about the 5th of February, in the range 12 to 16°C (54 to 61°F). The maximum Zero sea temperatures at the beginning of September require something like a 3/2mm fully sealed wetsuit. The minimum sea temperatures at Zero at the beginning 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 Zero 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 Zero.
