With kids back in school at this time and the leaf-peeping season not quite begun, hotel rates tend to be low and many fun local events fill up the calendar from agricultural fairs to sporting events. Shorter days and bursts of cool weather are a good reason to get outside in New England and if you travel towards the end of the month, you may even spy some hints of the region's famously vibrant autumn colors. New England Weather in September Across all six states, average high temperatures usually fall between 70 and 75 degrees Fahrenheit (21 and 24 degrees Celsius), while average lows fall between 50 and 57 degrees Fahrenheit (10 and 14 degrees Celsius). It's quite comfortable overall, although visits later in the month might start to feel chilly, especially at night. Average High Temp. Average Low Temp. Hartford, CT 75 F (24 C) 54 F (12 C) Providence, RI 74 F (23 C) 55 F (13 C) Boston, MA 72 F (22 C) 57 F (14 C) Hyannis, MA 71 F (22 C) 56 F (13 C) Burlington, VT 70 F (21 C) 51 F (11 C) North Conway, NH 70 F (21 C) 46 F (8 C) Portland, ME 70 F (21 C) 50 F (10 C) Fall officially begins in September, which means that there is an equal balance of daylight and nighttime hours. By September, summer's humidity is on its way out, thunderstorms are quieting down, and the ocean may still be holding onto their warmth. Throughout the month, about three inches of rainfall is typical but it will vary depending on where you are, so keep your eye on the forecasts. What To Pack Pack lightweight clothing for visits in early September, but be sure to bring along a jacket or sweatshirt, especially if you'll be in the mountains or near the coast. Temperatures will become increasingly cold at night as the month progresses, even when daytime temperatures are moderate and comfortable. In late September, you'll want at least one pair of long pants and a warmer jacket or raincoat. September isn't a particularly rainy month, but an umbrella is still a good idea.

September Travel Tips Autumn is apple season in New England, so keep your eye out for orchards where you can pick your own apples and indulge in apple cider doughnuts. New England is full of them. On the first Monday of September, many businesses, banks, and government offices may be closed for this Labor Day. The more north you travel and the later in the month it is, the better your chances are of seeing some colorful fall foliage. If you avoided Cape Cod, or other popular beach destinations, all summer because you didn't want to pay premium prices and contend with the weekend traffic, September will be a more affordable and less crowded time to go.
