La Seyne Sur Mer Water Temperature and Wetsuit Guide

Cold La Seyne Sur Mer water temperature (12 °C / 55 °F) today. Despite the sunshine, we suggest wearing a thick winter wetsuit, and ideally a neoprene hood, gloves and boots too because of the windchill will make air temperatures feel close to freezing.

Below is a graph of Historical Sea Surface Temperature for La Seyne Sur Mer. 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.

La Seyne Sur Mer water temperatures peak in the range 22 to 26°C (72 to 79°F) on around the 15th of August and are at their lowest on about the 29th of February, in the range 12 to 13°C (54 to 55°F). La Seyne Sur Mer water temperatures are always warm reach their highest in mid August. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The lowest water temperatures at La Seyne Sur Mer in late 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 La Seyne Sur Mer 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 La Seyne Sur Mer.
