Portsmouth is a city in Rockingham County, New Hampshire, in the United States. It is the only city in the county, but only the fourth-largest community, with a population of 21,233 at the 2010 census. A historic seaport and popular summer tourist destination, Portsmouth was the home of the Strategic Air Command’s Pease Air Force Base, later converted to Portsmouth International Airport at Pease with limited commercial air service.
It is also the center of a growing metropolitian region, often called, „The Seacoast,“ that is home to 125,000 and includes the coastal towns of Rye, Hampton, and Newcastle in New Hampshire and Kittery and York in Maine, as well as the inland cities of of Rochester and Dover, NH. This region is known for its high quality of life and ranks as the 16th safest region in the United States according to Morgan Quitno’s 2003 report. Today, you will still find an old styled barbershop as well as upscale coffee shops, a shop selling handmade gourmet chocolates across from a cooperative art gallery, and a slick seafood restaurant that could be in LA (the owners were from LA) next to place called the Friendly Toast that is decorated with 70s kitsch purchased on eBay.
Although the city has attracted an influx of newer residents who have come for the small town with big city amenities in the midst of an area of great natural beauty, the city still retains a good measure of stubborn independent spirit.
Portsmouth has a humid continental climate in spite of its maritime position, due to prevailing inland winds. Summers are moderately warm with winter days averaging around the freezing point, but with cold nights bringing it below the required −3 °C isotherm to have a humid continental climate. With high year-round precipitation, the cold winters can often be very snowy and summers wet.
