Located in southernmost New Hampshire, just four miles north of the Massachusetts border, Nashua perches on the east bank of the Merrimack River. Manchester lies 15 miles to the north. The Nashua River runs east-west through the city. The thin, rocky soil in the Merrimack Valley plain is better suited for sustaining forests than for producing agricultural crops. Nashua is part of a designation known as the "Golden Triangle," which includes Manchester and Salem, New Hampshire as well. The area surrounding Nashua is called the Gateways Region and takes in 14 communities.
Fall in Nashua is lovely and summers are warm and mostly free of humidity. Autumn brings crisp, clear days, and winters can be very cold with lots of snow. Dramatic and sudden weather changes can produce fog, hail, rain and snow storms and, on occasion, flooding.
