Below is a graph of Historical Sea Surface Temperature for Flynns Reef. 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.

Flynns Reef Water Temperature Graph

All of the graphs for the surf breaks presented on are on the same scale to enable comparison between locations around the world.

Flynns Reef sea temperatures peak in the range 17 to 20°C (63 to 68°F) on around the 28th of February and are at their lowest on about the 16th of August, in the range 12 to 13°C (54 to 55°F). The maximum Flynns Reef sea temperatures in the fourth week of February require something like a 3/2mm fully sealed wetsuit. The lowest sea temperatures at Flynns Reef in the middle of August are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days.

Actual sea surface water temperatures close to shore at Flynns Reef 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 Flynns Reef.
