Merimbula Bar 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.

Merimbula Bar sea water temperatures peak in the range 19 to 22°C (66 to 72°F) on around the 5th of February and are at their coldest on about the 8th of August, in the range 13 to 16°C (55 to 61°F). Merimbula Bar sea water temperatures are highest at the beginning of February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The coldest sea water temperatures at Merimbula Bar in early to mid 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 Merimbula Bar 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 Merimbula Bar.
