Herolds Bay sea temperatures peak in the range 20 to 24°C (68 to 75°F) on around the 29th of January and are at their coldest on about the 16th of July, in the range 16 to 18°C (61 to 64°F). Herolds Bay sea temperatures are warmest in late January. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.

Actual sea surface water temperatures close to shore at Herolds 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 Herolds Bay.
