Hampton Beach sea temperatures peak in the range 18 to 22°C (64 to 72°F) on around the 10th of August and are at their coldest on about the 1st of March, in the range 2 to 4°C (36 to 39°F). The warmest Hampton Beach sea temperatures in early to mid August require something like a 3/2mm fully sealed wetsuit. The coldest sea temperatures at Hampton Beach mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here at the beginning of March.
Actual sea surface water temperatures close to shore at Hampton 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 Hampton Beach.
