    Larmor Plage water temperatures peak in the range 17 to 20°C (63 to 68°F) on around the 14th of August and are at their minimum on about the 1st of March, in the range 10 to 11°C (50 to 52°F). The warmest Larmor Plage water temperatures in mid August require something like a 3/2mm fully sealed wetsuit. At its minimum at the beginning of March, low water temperatures at Larmor Plage are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

    Actual sea surface water temperatures close to shore at Larmor Plage 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 Larmor Plage.
