Treskostraal Water Temperature Graph

All of the graphs for the surf breaks presented on are on the same scale to enable comparison between locations around the world.

Treskostraal water temperatures peak in the range 18 to 22°C (64 to 72°F) on around the 3rd of February and are at their minimum on about the 10th of August, in the range 14 to 16°C (57 to 61°F). The warmest Treskostraal water temperatures at the start of February require something like a 3/2mm fully sealed wetsuit. The minimum seasonal water temperatures at Treskostraal in early to mid August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots.

Actual sea surface water temperatures close to shore at Treskostraal 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 Treskostraal.
