A hot sunny day, feeling like 31 °C even after we account for wind, and warm water temperature (23 °C) too at Siyayi. Surfers may need a thin summer wetsuit or at least a rash vest to block the UV. Otherwise, warm enough for just board shorts.

Siyayi Water Temperature Graph

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.

Siyayi sea water temperatures peak in the range 25 to 27°C (77 to 81°F) on around the 4th of February and are at their coldest on about the 1st of August, in the range 20 to 22°C (68 to 72°F). Year round warm sea water temperatures at Siyayi climb to their highest in early February. Even then a rash vest and board shorts should be fine for surfing at any time of year. Siyayi sea water temperatures are coldest at the beginning of August. 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 Siyayi 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 Siyayi.
