Diving in New Hampshire

Explore diving in New Hampshire

New Hampshire is one of the smaller states in the U.S, but that doesn’t mean there isn’t plenty of great diving sites to choose from.

Duck Island, The Isles of Shoals and The Lady of The Lake are some of New Hampshire’s most popular spots amongst local divers. Duck Island is famous for its regular seal encounters. These curios harbour and grey seals are usually juveniles and love being playful with the divers. When they get bored with the divers, they tend to go play with the nearby lobsters, ropes and seaweed.

Beyond the seals, the Isle of Shoals is gorgeous and a must see location for any diver visiting New England. The sea floor is covered in beautiful green and red kelp beds. Rock formations, boulders and overhangs create wonderful structures for eels, dogfish, crabs and squid.

When to dive in New Hampshire

Scuba diving around New Hampshire can take place in almost any weather and sea conditions.

As with any cold water diving, visibility can be limited and it is recommended to wear a 7mm wetsuit in the warmer months. Many divers opt for a dry suit in the cooler months.
