Widemouth Bay sea temperatures peak in the range 15 to 18°C (59 to 64°F) on around the 13th of August and are at their minimum on about the 1st of March, in the range 8 to 9°C (46 to 48°F). The maximum seasonal sea temperatures at Widemouth Bay in the third week of August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The minimum sea temperatures at Widemouth Bay mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here at the beginning of March.

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