Best Time to Fly to Boston: Seasons, Weather & Prices

Boston runs on calendars that most cities do not have. It is a major tourist city with a short, glorious summer and the most famous fall foliage in the country, but it is also a college town on an enormous scale, with dozens of universities whose move-in days, parents’ weekends and graduations fill every hotel in the city several times a year. Add a medical and biotech economy that keeps the convention center busy, the oldest annual marathon in the world, a regatta that brings rowing crews from across the globe, and four professional teams with devoted followings, and you have a city where hotel rates, more than airfares, decide the real cost of a trip. The weather matters too: Boston winters are cold, snowy and occasionally stormy, and its springs arrive late. This guide walks through the weather month by month, the fare seasons, the events that move prices, and how to handle the airport.

The short answer

For the best combination of weather and value, aim for early June, before the summer peak takes hold, and the first half of November, when the foliage crowds have gone but the city is still mild and lively. Late September and October are the most beautiful weeks of the year, with crisp days and the leaves turning across New England, and also the most expensive, with hotel rates that rank among the highest in the country. The cheapest fares and rooms come in January, February and early March, outside the school vacation week in February. The priciest stretches are September and October, graduation weekends in May, Marathon weekend in April, and July and August for airfares. Whatever you choose, run a flexible-date search on our Boston flights page; moving a trip by a few days around a graduation or a holiday weekend can change the hotel bill far more than the fare.

Boston’s weather, season by season

Boston sits on the Atlantic at the edge of a sheltered harbor, and the ocean shapes its weather in every season. Winters are cold and damp, with snow most years and a nor’easter or two capable of dropping a foot or more in a day; spring is late, cool and changeable, especially near the water; summers are warm and sometimes humid, with a sea breeze that can make the waterfront several degrees cooler than the suburbs; and fall is long, dry and bright. The figures below are approximate seasonal patterns based on the long-term Logan Airport climate normals from NOAA’s National Weather Service; check the current forecast before you pack, because a week in March or November can hold both a mild afternoon and a snowstorm.

Three things the table cannot show. First, the nor’easter: a coastal storm that tracks up the Atlantic and can bring heavy snow, high winds and coastal flooding, usually between December and March. Most years bring at least one, and when one is forecast, flights cancel pre-emptively and the city slows for a day or two. Second, the sea breeze: on a spring or early summer afternoon, the wind can turn onshore and drop the temperature on the waterfront by 5 to 10 degrees in an hour, so a warm morning in the Public Garden does not guarantee a warm evening in the Seaport. Third, humidity: the numbers for July and August look moderate, but a humid week in the upper 80s °F feels a good deal hotter, and many older buildings and triple-deckers are not air-conditioned.

How Boston’s fare seasons work

Four calendars drive demand for Boston: summer tourism, which fills the flights from June to August; the academic year, which sends a wave of students and parents through the city at the start of September, again on parents’ weekends in October, and again at graduation in May; the fall foliage, which makes late September and October the peak for hotels and for travelers heading on to Vermont, New Hampshire and Maine; and the conventions and medical meetings, which fill downtown and the Seaport on weekdays at any time of year. The result is an unusual pattern in which airfares peak in summer but hotel rates peak in the fall, and the two do not always move together. Boston Logan is also a busy, competitive airport, with JetBlue as its largest carrier and all the major airlines present, which helps keep fares on many domestic routes reasonable even when rooms are not.

Peak season

June through October, plus graduation weekends, Marathon weekend and the week between Christmas and New Year. Summer airfares are at their highest in July and early August, when families travel and the Cape Cod crowds pass through Logan. From Labor Day to the end of October, hotel rates climb to the year’s maximum: the students are back, conventions return, the weather is at its best, and leaf-peepers from around the world use Boston as the gateway to New England. If you must travel in peak, book the hotel early, consider Cambridge, Brookline or a hotel near a T station farther out, and fly mid-week.

Shoulder season

April to May and November. April is cool but green by the end of the month, with baseball back at Fenway, and May is lovely, but both carry spikes, for the Marathon and for commencements, that can make a single weekend as expensive as October. November, once the leaves have fallen, is the value month of the fall: mild in the first half, quiet, and with hotel rates well down from their October highs, until Thanksgiving week pushes fares up again.

Low season

January through mid-March, outside the holidays and school vacation week. Fares and rooms are at their lowest, the museums are uncrowded, the Celtics and Bruins are in season, and the city is cold but entirely functional. The trade-off is weather: build a buffer into connections, because a nor’easter can ground flights for a day. Early December, before the holiday rush, is another quiet, inexpensive window.

As elsewhere, mid-week departures and early or late flights usually price below Friday and Sunday afternoons on the same route, and a search across a whole month reveals cheaper pairs of dates close to your first choice. Our guide to the best times to book explains how to read those patterns.

Boston month by month

January

Cold, often snowy and, after the first week, one of the cheapest months of the year for both flights and hotels. The Celtics and Bruins play at TD Garden, the Frog Pond rink on Boston Common is open for skating, and the museums, the Museum of Fine Arts, the Gardner, the Museum of Science, are at their quietest. Pack for real cold and plan indoor days; the city handles snow well, and the T keeps running.

February

Similar weather and often the snowiest month, with low fares outside Presidents’ Day weekend (the third Monday of February) and the Massachusetts school vacation week that surrounds it, when local families travel and flights out of Boston and hotels in the ski country fill. A good month for a museum, food and hockey weekend.

March

Gray, changeable and usually cheap. The St. Patrick’s Day parade through South Boston, held on the Sunday around March 17, is one of the biggest in the country and fills the bars for the weekend. College spring breaks empty the student neighborhoods for a week or two, and a late snowstorm is always possible.

April

Spring arrives slowly, and the calendar gets busy. Patriots’ Day, the third Monday of April, brings the Boston Marathon, reenactments at Lexington and Concord at dawn, and a Red Sox morning game at Fenway, and hotel rates around the course and in Back Bay are among the highest of the year that weekend. The Massachusetts school vacation week falls the same week. Opening Day at Fenway, the magnolias on Commonwealth Avenue in the last week of the month, and the Swan Boats’ return to the Public Garden lagoon mark the start of the season.

May

Green, pleasant and, on the right weekends, very expensive. Commencement season runs through the second half of the month, when Harvard, MIT, Boston University, Northeastern, Boston College and dozens of other schools hold graduations, and families book hotels a year ahead; if your dates coincide, look well outside the city. The Boston Calling music festival fills Memorial Day weekend. The weekdays between the big weekends are much better value.

June

Often the best month for weather, with long evenings and warmth without the full humidity of July. Harbor ferries run on their summer schedules, Pride fills the city early in the month, and Harborfest begins in the last days of June. Fares rise as schools finish; the first two weeks are the value play.

July

Peak summer. The Fourth of July brings the Boston Pops concert and fireworks at the Hatch Shell on the Esplanade, one of the most famous Independence Day celebrations in the country, and the USS Constitution’s annual turnaround cruise in the harbor. Airfares are at their summer high, the Harbor Islands and Cape Cod are at their best, and the North End’s saints’ feasts begin on summer weekends. Expect humid spells and thunderstorms.

August

Warm and humid, with the North End feasts, the biggest of which closes the neighborhood’s streets on the last weekend of the month. The final days of August and the first of September bring the city’s strangest event: the mass move-in, when tens of thousands of students arrive at once and apartment leases turn over, rental trucks clog the streets, and hotels near the universities sell out. Avoid those days if you can.

September

Many Bostonians would say this is the best month of the year: warm days, cool nights, low humidity and the whole city back from vacation. It is also where hotel rates reach their annual peak, with conventions, parents’ weekends and pennant races at Fenway all competing for rooms. Airfares are moderate after Labor Day, so the hotel is the number to watch.

October

The postcard month. The foliage turns across New England through the month, starting in the northern mountains in late September and reaching the Boston area in the second half of October; the Indigenous Peoples’ Day (Columbus Day) weekend, the second Monday, is the busiest leaf-peeping weekend of the year. The Head of the Charles Regatta fills the river and the hotels for a weekend in the second half of the month, and Salem’s month of Halloween events draws huge crowds on weekends. Book early.

November

Rates fall steadily once the leaves are down, and the first half of the month is often mild enough for walking the Freedom Trail in a light jacket. Thanksgiving, the fourth Thursday, sends fares up for the week; Plymouth, an hour south, marks the holiday in style. The holiday lights go up on Boston Common late in the month.

December

Two months in one. The first half is quiet and inexpensive, with the tree lighting on the Common, holiday markets, the Boston Pops holiday concerts at Symphony Hall and the reenactment of the Boston Tea Party on December 16. From about December 18, fares rise sharply for Christmas and New Year, and the city celebrates New Year’s Eve with First Night events and fireworks over the harbor.

Events that move Boston flight and hotel prices

Cross-check these against your dates before you book. Exact dates shift each year; Meet Boston, the city’s tourism bureau, keeps the current calendar.

• Presidents’ Day weekend and February school vacation (third week of February).
• St. Patrick’s Day parade (the Sunday around March 17).
• Boston Marathon and Patriots’ Day (third Monday of April): a severe hotel spike across Back Bay and downtown.
• Commencement weekends (second half of May): rooms sell out months ahead across the city and Cambridge.
• Fourth of July and Harborfest.
• Student move-in (the last days of August and September 1) and parents’ weekends in October.
• Foliage season and the Head of the Charles (October): the highest hotel rates of the year.
• Thanksgiving week and Christmas to New Year.
• Red Sox, Celtics, Bruins and Patriots home games, playoff runs and stadium concerts. Our Boston events page shows what is on sale for your dates.
• Medical and technology conventions at the Seaport, which can fill downtown hotels on weeknights without warning; if mid-week rates look strangely high, that is usually why.

Getting in from the airport

Boston is served by Boston Logan International (BOS), in East Boston on the far side of the harbor and only about 5 kilometers (3 miles) from downtown, which makes it one of the most convenient major airports in the country. It has four terminals, A, B, C and E, with Terminal E handling most international flights, and there are nonstop flights from nearly every large U.S. city and from dozens of destinations in Europe and beyond. Getting downtown is easy. The Silver Line SL1 bus runs from every terminal to South Station, where it connects with the Red Line, Amtrak and commuter rail, and has been free to board at the airport in recent years; free Massport shuttle buses link the terminals to Airport station on the Blue Line, which reaches downtown in minutes; water taxis cross the harbor to the waterfront; and taxis and ride-hail reach downtown through the harbor tunnels in 15 to 30 minutes when traffic is light. Logan Express buses run to Back Bay and several suburbs. Two alternatives are worth checking when Logan fares are high: Providence (PVD), about an hour south, has its own MBTA commuter rail station, and Manchester-Boston Regional (MHT) in New Hampshire is about an hour north by car. Our Boston car-versus-transit guide explains why most visitors do not need a car, and our Logan airport guide covers the layout.

Timing tricks that work for Boston

• Search the whole month. Boston’s spikes are narrow: a graduation weekend or Marathon Monday can sit beside perfectly normal dates. A calendar search on TicketScanner shows the edges instantly.
• Price the hotel first in the fall and in May. In September, October and on commencement weekends, the room costs more than the flight. Run a Boston hotel search for the same dates before you commit.
• Look across the river. Cambridge and Somerville hotels on the Red Line can be cheaper than Back Bay on weekends, and business-district hotels in the Seaport and the Financial District often drop their rates on Friday and Saturday nights.
• Fly mid-week. Boston’s business and university traffic makes Monday morning and Friday and Sunday afternoon the busiest flights; Tuesday to Thursday is usually the value.
• Check Providence and Manchester. A cheaper fare into PVD with a commuter rail ride, or into MHT with a rental car, can beat Logan, especially in summer.
• Build a winter buffer. Nor’easters can ground flights for a day between December and March; avoid tight connections, and read our guide to how early to arrive at the airport.
• Flying out of Boston instead? The same seasonality applies in reverse; see cheap flights from Boston.

What to pack, by season

Winter (December to March): a warm, waterproof coat, a hat, gloves and boots with grip for slushy sidewalks and icy brick. Spring (April to May): layers, a rain jacket and a sweater for the evenings, especially near the water. Summer (June to August): light, breathable clothing, sunscreen, an umbrella for thunderstorms and a light layer for air-conditioned museums and harbor cruises. Fall (September to November): layers and a medium jacket, heavier by November. In any season, bring comfortable shoes: Boston’s brick sidewalks and cobblestones are hard on thin soles, and you will walk more than you expect.

The best time to fly to Boston for…

Fall foliage

Early to mid-October for the mountains of Vermont, New Hampshire and Maine, and the second half of October for Boston itself, booked months in advance.

The Marathon

Patriots’ Day weekend in April, with the hotel booked as soon as you have a bib or a plan, or stay outside the city on a T line.

Baseball at Fenway

June, when the weather is warm but not humid, or September for the pennant race; April games are often cold.

The lowest fares

January through early March, outside Presidents’ Day week, and early December. Pair with museums, restaurants and a Celtics or Bruins game.

Families

Late June and early July, for the Harbor Islands, the Aquarium and the Fourth of July, or the first half of November for smaller crowds and lower rates.

International visitors

Travelers from Visa Waiver Program countries need an approved ESTA before boarding; most others need a visa. The State Department’s travel site explains what applies to you, and the TSA lists what you can carry through security.

Frequently asked questions

What is the cheapest month to fly to Boston?

January and February are consistently the lowest for both flights and hotels, outside the February school vacation week, followed by early March and early December.

What is the best month to visit Boston for weather?

June and September, with October close behind for crisp days and foliage. July and August are warm and can be humid; winter is cold and snowy.

When is fall foliage in Boston?

The color reaches the Boston area in the second half of October, after peaking earlier in northern New England. The Arnold Arboretum and the Public Garden are the best places to see it in the city.

Why are Boston hotels so expensive in the fall?

Because everything happens at once: the students are back, the convention calendar is full, the weather is at its best and foliage visitors use Boston as their base. September and October are among the most expensive months of any American city.

Should I avoid Boston in winter?

Not if you pack for it. January and February are cold, but they bring the lowest prices, empty museums and hockey and basketball season. Allow for a possible storm delay.

How far ahead should I book?

For graduation weekends, the Marathon and October, book the hotel months ahead. For winter and November, finding the right dates matters more than booking early.

Is it better to fly into Boston or Providence?

Boston for convenience, since Logan is minutes from downtown. Providence is worth checking when Logan fares are high, with a commuter rail link from the airport to the city.
