    Tarantulas 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.

    Tarantulas sea water temperatures peak in the range 16 to 19°C (61 to 66°F) on around the 4th of September and are at their lowest on about the 24th of February, in the range 12 to 15°C (54 to 59°F). The maximum seasonal sea water temperatures at Tarantulas in early September lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The lowest sea water temperatures at Tarantulas in the fourth week 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 Tarantulas 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 Tarantulas.
