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. Matsube Bay water temperatures peak in the range 26 to 28°C (79 to 82°F) on around the 13th of August and are at their coldest on about the 29th of February, in the range 15 to 17°C (59 to 63°F). Year round warm water temperatures at Matsube Bay climb to their warmest in the third week of August. Even then a rash vest and board shorts should be fine for surfing at any time of year. The coldest seasonal water temperatures at Matsube Bay in late February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. Actual sea surface water temperatures close to shore at Matsube 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 Matsube Bay.
