Below is a graph of Historical Sea Surface Temperature for Cow Bay. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.

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.

Cow Bay sea water temperatures peak in the range 15 to 18°C (59 to 64°F) on around the 11th of August and are at their lowest on about the 19th of February, in the range -0 to 2°C (32 to 36°F). The highest seasonal sea water temperatures at Cow Bay in the second week of August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The lowest sea water temperatures at Cow 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 in the third week of February.

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