    Flatrock 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.

    Flatrock water temperatures peak in the range 19 to 21°C (66 to 70°F) on around the 1st of March and are at their coldest on about the 12th of September, in the range 14 to 16°C (57 to 61°F). The maximum Flatrock water temperatures at the beginning of March require something like a 3/2mm fully sealed wetsuit. The coldest water temperatures at Flatrock in the second week of September 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 Flatrock 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 Flatrock.
