What Is the Weather Like in Boston in October?
Boston's October weather changes noticeably as the month progresses. The average October high is about 62°F (17°C), while the average low is about 48°F (9°C).
Early October can still feel fairly mild during the afternoon, with temperatures sometimes reaching the upper 60s or warmer. By the end of the month, afternoons are more likely to be in the 50s or low 60s, and nighttime temperatures can fall into the 40s.
The changing weather is part of what makes October such a popular time to visit Boston. Fall foliage is developing around the region, and the cooler temperatures are generally comfortable for walking and sightseeing.
If you're planning to spend several hours outdoors, especially on a walking tour, it's a good idea to check the forecast before heading out and dress in layers.
How Much Rain Does Boston Get in October?
October is a moderately wet month in Boston, with an average of about 4 inches of precipitation during the month. Measurable precipitation occurs on roughly 10 or 11 days in a typical October.
Rain doesn't necessarily mean you'll lose an entire day of sightseeing. October weather can change quickly, and many rainy periods are brief. It's still a good idea to check the forecast each morning and have a rain jacket or compact umbrella available.
If you're planning to spend a lot of time walking around Boston, comfortable water-resistant shoes can also be helpful, particularly later in the month.
Does It Snow in Boston in October?
Snow is very unusual in Boston in October. While a trace of snow has occasionally been recorded late in the month, measurable snowfall is rare.
You should be much more concerned about rain than snow when planning an October visit. If you're visiting toward the end of the month, however, cooler temperatures make a warm jacket a good idea.
What to Wear in Boston in October
The best approach to dressing for Boston in October is to wear layers. Temperatures can vary considerably between the afternoon and evening, and the weather can change from one day to the next.
For most October visits, consider bringing:
- Long-sleeve shirts or lightweight tops
- Sweaters or fleece layers
- A medium-weight jacket
- Comfortable walking shoes
- A compact umbrella or rain jacket
- Warmer layers for evenings and late October
Early in the month, you may be comfortable in lighter clothing during the afternoon. Later in October, you'll probably want a warmer jacket, particularly after sunset.
Comfortable walking shoes are especially important in Boston. Many of the city's most interesting neighborhoods and historic sights are best explored on foot, and you'll likely spend more time walking than you expect.
What to Do in Boston in October
The cooler temperatures make October an excellent month for sightseeing in Boston. You can spend time outdoors without the heat and humidity of summer, while the fall foliage adds another reason to explore the city and surrounding area.
Here are some popular things to do in Boston and the surrounding area in October.
1. Take a Boston Walking Tour
October is an excellent time to explore Boston on foot. The city's historic neighborhoods, Freedom Trail, Beacon Hill, and downtown sights are particularly enjoyable when temperatures are cool enough for comfortable walking.
Our Boston walking tours offer several ways to explore the city with a guide and learn more about its history and landmarks.
See our Boston walking tours and check the schedule for October.
2. Visit Salem
October is one of the busiest times of year to visit Salem, especially because of the city's connection to the 1692 witch trials and its extensive Halloween celebrations.
If you plan to visit during October, allow extra time for transportation and expect larger crowds, particularly on weekends and around Halloween.
If you'd like to travel from Boston by boat, see our guide to how to take the ferry from Boston to Salem for information about the ferry and what to expect.
3. Go Leaf-Peeping
October is a great time to see fall foliage in and around Boston. The timing varies from year to year and depends on weather conditions, but color generally develops earlier in northern New England and later around Boston and the coast.
You don't necessarily need to leave the city to enjoy fall colors. Boston's parks, green spaces, and historic neighborhoods can be beautiful in October, while a trip farther into New England can provide even more spectacular foliage.
4. Go Whale Watching
If you're visiting Boston early in October, you may still be able to take a whale-watching cruise from the city.
Whale-watching season generally runs through the fall, although schedules and wildlife sightings depend on weather and conditions at sea. Check the current cruise schedule before planning your trip.
5. Visit the New England Aquarium
The New England Aquarium is a good option when the weather isn't cooperating or when you want to spend part of the day indoors.
The aquarium features marine animals and exhibits from around the world, including its large central ocean tank. It's also located on Boston's waterfront, making it easy to combine with other downtown sightseeing.
6. Visit the New England Sports Museum
Sports fans can visit the New England Sports Museum at TD Garden to learn about the history of Boston's professional sports teams.
The museum features memorabilia, exhibits, and stories connected to teams including the Boston Celtics and Boston Bruins.
It's particularly convenient if you're already exploring the North End or visiting TD Garden.
7. Take a Samuel Adams Brewery Tour
Beer enthusiasts can visit the Samuel Adams Boston Brewery in Jamaica Plain for brewery tours and tastings.
October is a good time to visit a brewery if you want to take a break from sightseeing outdoors. Check the brewery's current schedule and tour options before you go.
8. Explore Faneuil Hall Marketplace
Faneuil Hall Marketplace is a popular stop in downtown Boston, with shops, restaurants, food vendors, and historic surroundings.
October's cooler weather makes it comfortable to explore the area on foot and continue toward the waterfront or other downtown attractions.
For more information, see our guide to Faneuil Hall and Quincy Market.
9. Take a Ghost Tour
October is a natural time to explore Boston's darker history after sunset. A ghost tour can combine local history with stories about some of the city's more mysterious locations.
It's also a good way to experience Boston after dark when the weather is cool but generally not yet winter-like.
10. Consider a Tourist Pass
If you're planning to visit several of Boston's paid attractions, a tourist pass may help you save money compared with purchasing individual tickets.
Before buying a pass, compare the attractions included with your own itinerary to make sure you'll get enough value from it.
See our guide to Go Boston Card vs. CityPASS for a comparison of the options.
