Bethune Beach sea water temperatures are minimum in the second week of February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.

Actual sea surface water temperatures close to shore at Bethune Beach 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 Bethune Beach.
