    Donkin Bay sea temperatures peak in the range 18 to 20°C (64 to 68°F) on around the 22nd of January and are at their coldest on about the 17th of July, in the range 14 to 16°C (57 to 61°F). The maximum Donkin Bay sea temperatures in the second half of January require something like a 3/2mm fully sealed wetsuit. The coldest sea temperatures at Donkin Bay in the middle of July 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 Donkin 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 Donkin Bay.
