The maximum Trez Hir sea temperatures in early to mid August require something like a 3/2mm fully sealed wetsuit.

You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at Trez Hir 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 Trez Hir.
