A hot and sunny day, feeling like 31 °C even after we account for wind, and very warm water temperature (27 °C) too at Hapuna. Surfers may need a thin summer wetsuit or at least a rash vest to block the UV.

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

Hapuna 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.

Hapuna water temperatures peak in the range 26 to 28°C (79 to 82°F) on around the 3rd of September and are at their minimum on about the 13th of February, in the range 24 to 25°C (75 to 77°F). Year round warm water temperatures at Hapuna climb to their highest at the start of September. Even then a rash vest and board shorts should be fine for surfing at any time of year. Hapuna water temperatures are always warm but dip to their minimum in the third week of February. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy.

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

 

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
