Middleton Beach sea temperatures peak in the range 19 to 20°C (66 to 68°F) on around the 1st of March and are at their minimum on about the 8th of September, in the range 15 to 17°C (59 to 63°F). The highest Middleton Beach sea temperatures at the beginning of March require something like a 3/2mm fully sealed wetsuit. The minimum seasonal sea temperatures at Middleton Beach in early to mid September 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 Middleton 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 Middleton Beach.
