    Moonlight Beach 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.

    Moonlight Beach water temperatures peak in the range 19 to 22°C (66 to 72°F) on around the 5th of September and are at their coldest on about the 5th of February, in the range 13 to 16°C (55 to 61°F). Moonlight Beach water temperatures are maximum at the beginning of September. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The coldest water temperatures at Moonlight Beach at the beginning of February 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 Moonlight Beach 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 Moonlight Beach.
