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.
Shelly Beach sea water temperatures peak in the range 24 to 27°C (75 to 81°F) on around the 6th of February and are at their coldest on about the 15th of August, in the range 19 to 20°C (66 to 68°F). Year round warm sea water temperatures at Shelly Beach climb to their warmest in the first week of February. Even then a rash vest and board shorts should be fine for surfing at any time of year. The coldest Shelly Beach sea water temperatures in mid August require something like a 3/2mm fully sealed wetsuit.
Actual sea surface water temperatures close to shore at Shelly Beach 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 Shelly Beach.
