A hot and sunny day, feeling like 31 °C even after we account for wind, and very warm water temperature (28 °C) too at Green Bay. Surfers may need a thin summer wetsuit or at least a rash vest to block the UV.

Below is a graph of Historical Sea Surface Temperature for Green 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.

Green Bay 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.

Green Bay sea temperatures peak in the range 28 to 29°C (82 to 84°F) on around the 22nd of July and are at their lowest on about the 29th of January, in the range 18 to 21°C (64 to 70°F). Year round warm sea temperatures at Green Bay climb to their maximum in the second half of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. The lowest Green Bay sea temperatures in late January require something like a 3/2mm fully sealed wetsuit.

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