We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

Portland 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.

Portland sea temperatures peak in the range 16 to 18°C (61 to 64°F) on around the 16th of February and are at their coldest on about the 12th of September, in the range 13 to 15°C (55 to 59°F). The highest seasonal sea temperatures at Portland in the middle of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The coldest sea temperatures at Portland in the second week of September 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 Portland 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 Portland.
