Seaside Cove 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.

Seaside Cove water temperatures peak in the range 13 to 17°C (55 to 63°F) on around the 18th of August and are at their lowest on about the 8th of February, in the range 7 to 11°C (45 to 52°F). The maximum seasonal water temperatures at Seaside Cove in the third week of August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. At its lowest in early to mid February, low water temperatures at Seaside Cove are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at Seaside Cove 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 Seaside Cove.
