Whangamata Estuary 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.

Whangamata Estuary water temperatures peak in the range 19 to 22°C (66 to 72°F) on around the 7th of February and are at their lowest on about the 20th of August, in the range 13 to 15°C (55 to 59°F). Whangamata Estuary water temperatures are highest in the first part of February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.

Actual sea surface water temperatures close to shore at Whangamata Estuary 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 Whangamata Estuary.
