Statistics for 22 Jun (1981–2005) – mean: 25.5 °C, range: 24.3 °C to 27.6 °C

Sunny with very warm air temperatures, feeling like 26 °C once we account for any wind. Sea temperatures (24 °C) warm too. Staying warm in the water won't be a problem in board-shorts, but wear at least a rash-vest to keep the UV off.

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

Aoshima 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.

Aoshima sea temperatures peak in the range 27 to 30°C (81 to 86°F) on around the 6th of August and are at their lowest on about the 1st of March, in the range 18 to 20°C (64 to 68°F). Year round warm sea temperatures at Aoshima climb to their warmest in the first week of August. Even then a rash vest and board shorts should be fine for surfing at any time of year. The lowest Aoshima sea temperatures at the beginning of March require something like a 3/2mm fully sealed wetsuit.

Actual sea surface water temperatures close to shore at Aoshima 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 Aoshima.
