Mad River Beach sea temperatures peak in the range 12 to 17°C (54 to 63°F) on around the 22nd of August and are at their coldest on about the 31st of March, in the range 10 to 13°C (50 to 55°F). The maximum sea temperatures at Mad River Beach in the second half 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. At its coldest at the end of March, low sea temperatures at Mad River Beach are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at Mad River Beach 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 Mad River Beach.
