The water temperature (14 °C) at Maraenui is not too cold today but the windchill (4 °C) will make the air temperature seem much colder than the sea and it is forecast to be cloudy too so a chilly prospect. You'll need at least a hooded spring wetsuit to keep surf at Maraenui today, maybe neoprene boots and gloves too.

Maraenui 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.

Maraenui sea temperatures peak in the range 19 to 22°C (66 to 72°F) on around the 9th of February and are at their lowest on about the 23rd of August, in the range 14 to 15°C (57 to 59°F). Maraenui sea temperatures are highest in early to mid February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The lowest sea temperatures at Maraenui in the fourth week of 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 Maraenui 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 Maraenui.
