Boston weather during September is usually balmy with low humidity, making this one of the very best months to visit the city. 

With the heat of the summer behind us, lots of outdoors festivals, art walks, and concerts take advantage of the warm temperatures and bright blue skies.  Restaurants still offer patio dining - too good to miss!

If you're planning to visit Boston in September, knowing what kind of weather to expect will help you plan what to pack and what to do - so check out the weather information on this page.  The photo gallery below will show you what to expect.

Here are some representative photos showing Boston during September.  Notice how green the leave still are?  During most years, colorful fall foliage doesn't really begin to appear until the end of the month.  The best way to see autum color this month is on one of the popular foliage cruises to Maine and Canada.

Boston September Temperatures and Conditions

Boston's weather during September is ususally more predictable than almost any other month . . . too early for cold weather or snowstorms, too late in the year for many thunderstorms, and less humidity than during August.  It's a month of sunny, warm days, and crisp, cool evenings and nights.

Of course, most years do bring a fair amount of rain...slightly over 3 inches to be exact - so if you're planning a trip to Boston during September, you'll need to pack and plan activities with at least a little rain in mind.

Here are annual averages for September weather, although of course every year is unique:

Average September high temperature:  73° F
Average September low temperature: 57° F
Record high temperature for September:  102° F (1881)
Record low temperature for September:  34° F (1936)
Average precipitation for September:  3.14 inches

Be sure to check the Boston weather report before coming just in case something unusual, such as a nor'easter or a late-season hurricane is forecast. 

 

What to Pack for Boston in September

In addition to my regular suggestions about what to pack, bring clothes that will be perfect for daytime temperatures in the 70s and somewhat chiller evenings - but also be prepared for unexpected extremes.

That means packing a couple of sweaters or light jackets that you can wear at night, and layer if necessary if the temperature really drops.  A scarf or two will also be useful.  And definitely bring a waterproof rain jacket and/or umbrella or rain hat - remember those 3 inches of rain that will come sometime this month!

But also bring a couple of things that you'll be comfortable in if we have a heat wave with humidity.  Most local stores clear out this type of merchandise by early August, so you'll have a tough time if you try to do emergency shopping for hot-weather clothing. 

Keep in mind that if you're planning to go on one of the popular fall foliage tours this month, several of them go to cooler

 

Best Activities for Enjoying Boston September Weather

November is the perfect month for walking around the city and enjoying the last of the fall foliage, bright red seed pods hanging from small trees, many-hued chrysanthemums and other autumn blooms, and orange pumpkins left over from Halloween.  Even if the weather isn't so nice, dress warmly and go out anyway. 

Check out my recommendations for things to do in Boston in November, as well as my suggestions about Boston activities for rainy days.  If you're visiting with your children, take a look at the outdoor and indoor options on my best kids' activities recommendations.  And on cold nights, stay warm and have fun at Boston theaters, movies, bars and clubs, and restaurants.
