Cannon Beach Water Temperature Graph

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

Cannon Beach sea temperatures peak in the range 13 to 18°C (55 to 64°F) on around the 13th of August and are at their minimum on about the 6th of March, in the range 4 to 7°C (39 to 45°F). The highest sea temperatures at Cannon Beach in the third week 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. The minimum sea temperatures at Cannon Beach 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 in the first week of March.

Actual sea surface water temperatures close to shore at Cannon 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 Cannon Beach.
