Below is a graph of Historical Sea Surface Temperature for Marion Bay. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
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.
Marion Bay sea temperatures peak in the range 14 to 17°C (57 to 63°F) on around the 13th of February and are at their lowest on about the 7th of August, in the range 11 to 13°C (52 to 55°F). The highest seasonal sea temperatures at Marion Bay in the third week of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. At its lowest in the first part of August, low sea temperatures at Marion Bay 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 Marion Bay 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 Marion Bay.
