Lyall Bay sea temperatures peak in the range 16 to 19°C (61 to 66°F) on around the 7th of February and are at their minimum on about the 20th of August, in the range 11 to 13°C (52 to 55°F). The highest seasonal sea temperatures at Lyall Bay in the first part of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. At its minimum in mid to late August, low sea temperatures at Lyall 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 Lyall 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 Lyall Bay.
