Below is a graph of Historical Sea Surface Temperature for Rapahoe. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
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.
Rapahoe sea water temperatures peak in the range 16 to 20°C (61 to 68°F) on around the 7th of February and are at their minimum on about the 9th of August, in the range 11 to 13°C (52 to 55°F). The highest seasonal sea water temperatures at Rapahoe in the first part of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The minimum sea water temperatures at Rapahoe in early to mid August are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days.
Actual sea surface water temperatures close to shore at Rapahoe 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 Rapahoe.
