Below is a graph of Historical Sea Surface Temperature for Hawaii. 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.

Hawaii sea temperatures peak in the range 28 to 29°C (82 to 84°F) on around the 30th of August and are at their minimum on about the 1st of March, at 26°C. Year round warm sea temperatures at Hawaii mean that a rash vest and board shorts should be fine for surfing at any time of year

Actual sea surface water temperatures close to shore at Hawaii 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 Hawaii. Refer to our detailed weather forecasts for this information.
