Julias sea water temperatures peak in the range 21 to 23°C (70 to 73°F) on around the 10th of August and are at their lowest on about the 24th of February, in the range 15 to 17°C (59 to 63°F). Julias sea water temperatures are highest in early to mid August. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The lowest seasonal sea water temperatures at Julias in the fourth week of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots.
Actual sea surface water temperatures close to shore at Julias 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 Julias.
