Belt Road 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.

Belt Road sea water temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 8th of February and are at their coldest on about the 27th of August, in the range 12 to 14°C (54 to 57°F). The highest Belt Road sea water temperatures in early to mid February require something like a 3/2mm fully sealed wetsuit. The coldest sea water temperatures at Belt Road in the last days of August 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 Belt Road 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 Belt Road.
