New Hampshire climate

Typical of New England, New Hampshire has long and cold winters, short springs, mild summers, and beautiful autumns. Winter starts in November and lasts through March. In January the temperature hover around the zero degree (Celsius) mark. Snow is everywhere, but mostly in the White Mountains. Spring warms up to the 10s and mid-teens, with an occasional snowstorm.

  • Visit Yogi Bear’s Jellystone Park theme park. Its calendar of events is chock-full of happy occasions including Yogi’s Yuletide Christmas, held in July, and a delicious-sounding Chocolatemania weekend in August.
  • Mount Washington, the highest peak in the northeast, provides a winter wonderland for skiing, snowmobiling, hiking, ice fishing and sleigh rides. Getting to the top by Cog Railway takes three hours. The train climbs nearly 2km (6,288 feet) to the summit of the mountain. Driving to the top is dependant on the weather, but the roads are clear until mid-October. Mount Washington State Park covers 59 acres at the top and is surrounded by the White Mountain National Forest (750,000 acres). On a clear day you can see to Vermont, New York, Massachusetts, Maine, Quebec, and on to the Atlantic Ocean. Peaks of the Presidential Range of mountains in the White Mountains are named for prominent Americans, either public figures of the 18th and 19th centuries or Presidents.
  • The Ashuelot bridge is considered to be one of the state’s most elaborate covered bridges, while West Swanzey Bridge is considered the one of the most beautiful.
  • The Isles of Shoals are a group of nine small islands situated about 16km (10 miles) off the coast and straddling New Hampshire and Maine. Star Island, the second biggest (after Appledore Island) is served by boat from the mainland and is open to visitors. The Rutledge Marine Lab is open daily. Smuttynose Island is the third biggest and is where Blackbeard, the famous pirate, honeymooned with his fifteenth wife. Her ghost is said to haunt the island’s shores and Blackbeard’s buried treasure has yet to be discovered too.
