Ohara 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.

Ohara sea temperatures peak in the range 25 to 28°C (77 to 82°F) on around the 14th of August and are at their coldest on about the 1st of March, in the range 15 to 17°C (59 to 63°F). Year round warm sea temperatures at Ohara climb to their warmest in mid August. Even then a rash vest and board shorts should be fine for surfing at any time of year. The coldest seasonal sea temperatures at Ohara at the beginning of March 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 Ohara 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 Ohara.
