What September is like in Boston
September is Boston's best month. Highs sit near 74F (23C), nights turn cool, and the summer humidity breaks. The first weekend is hectic with college move-in, but after that the city settles into a lively, grown-up rhythm with a full events calendar. Prices are high, since it is a popular month, and late in the month the first fall color appears up north.
This month suits almost everyone, especially couples, history lovers, and families with younger kids not tied to school dates. The only thing to avoid is the move-in weekend. If you want peak fall color, plan for October, but expect bigger crowds and higher prices.
Make the most of September
What is especially good about Boston this month.
Perfect walking weather
Warm days and cool nights make this the best month for the Freedom Trail, the North End, and long walks along the Charles.
The first fall color
In late September, foliage starts in northern New England. A day trip north gives you an early taste of the color.
The last weeks at Fenway
The Red Sox regular season ends in September, and a warm evening game is a great way to spend a night.
What to pack for September
- A light jacket or sweater for cool evenings
- Comfortable walking shoes
- Layers for warm afternoons and crisp nights
- A compact umbrella
