What happens at 140 Main Street once the August fair packs up? The answer is on the Marshfield Fair's own upcoming events listing. It shows nine entries this fall and beyond. One is a car and helicopter show, and the other eight are the same event repeated once a month: the indoor winter farmers' market under the grandstand.
The fairgrounds' off-season is built around that monthly market. The bigger ticketed events this year land on top of it. Cars & Copters falls on the market's October Saturday. The new drive-through light show runs through the market's December Saturday and lights up the same grounds that evening. If you plan around the third Saturday, you have most of the season covered.
Eight Saturdays, one grandstand
The winter market meets on the third Saturday of each month from October through May, 10 a.m. to 1 p.m. It's held indoors under the lightly heated grandstand, and you enter through Gate A. Admission and parking are free, and the market's general information page describes the grounds as stroller- and wheelchair-friendly.
The summer market runs on a different schedule: Fridays from June through September, 2 to 6 p.m., indoors and outdoors by the grandstand, rain or shine. Some July and August dates move offsite. The winter version trades a weekly Friday afternoon for one Saturday morning a month, so each date carries more weight.
That's why each date has its own program. The market's music and events page lists a performer for every Saturday and adds a free talk or giveaway on some of them:
| Date | Live music | Also on the program |
|---|---|---|
| Sat., Oct. 17, 2026 | David Ogden | Cranberry giveaway and free talk |
| Sat., Nov. 21, 2026 | Harper and the Minstrel | Free native-plants talk |
| Sat., Dec. 19, 2026 | Chris Carter | |
| Sat., Jan. 16, 2027 | Rich O'Reilly | Sourdough-starter talk |
| Sat., Feb. 20, 2027 | Peter Mundt | |
| Sat., Mar. 20, 2027 | Chris Carter | |
| Sat., Apr. 17, 2027 | Harper and the Minstrel | |
| Sat., May 15, 2027 | Rich O'Reilly |
The market began in 2006 as a summer-only market. It added winter dates within a few years after customers asked for them, and the Marshfield Agricultural & Horticultural Society, which runs the fair, sponsors it. The market says about one-third of its vendors are Marshfield residents. Its offerings include local produce, pasture-raised animal products, prepared and baked foods, farm products and home goods.
Who's on the vendor roster
The current vendor roster includes local names alongside a few from farther afield:
- Farms: Bayberry Farm, Dias & Daughters Farm, Fowl Play Farm & Miss Bee Haven, North Star Farm, Summer Dreams Farm, River Street Gardens, The Wild Patch
- Seafood and pantry: Captain Marden's Seafoods, MFM Pantry, Courage Provisions, Righteous Ralph's BBQ Sauces, Honey I'm Home
- Baked goods and treats: Beulah's Bakery, Swanson Baking Company, All Belgium Waffles, Doce de Boston, Streetpops
- Other makers: Green Harbor Baskets, Table144, Adult and Teen Challenge
The roster page says it doesn't separate virtual dates from in-person ones. A name on the list doesn't mean that vendor will be under the grandstand on any given third Saturday. If you're going for a particular baker or farm in January, check the market's page or ask at the manager's booth first.
The market accepts SNAP/EBT and HIP, and it says matching may be available. The current offer is posted at the manager's booth. The market also matches WIC and senior coupons when funding allows.
October 17 brings two events to one property
The first winter market of the season shares its date with the biggest ticketed event on the fall calendar. The Fair's Cars & Copters event page lists the show for Saturday, Oct. 17, 2026, from 10 a.m. to 4 p.m., with Oct. 18 as the rain date. It bills the show as "New England's Largest Charity Car And Helicopter Show," presented by Q Car Care and Fly My Ride.
The organizer's own homepage and FAQ still show the earlier September date. The Fair's listing and the live ticket page both say Oct. 17, so that's the date to plan around.
Cars & Copters Inc. describes itself as a 501(c)(3) charity show. Its homepage names four beneficiaries: Cops for Kids with Cancer, Camp Jabberwocky, Boston Children's, and the Marshfield Boys and Girls Club. The organizer describes exotic and collector cars plus helicopters you can see up close, and its FAQ says food vendors will be on site. The sources describe helicopter displays, not rides.
When the ticket page was checked this fall, it listed these prices, fees included:
- Spectator general admission: $23
- Ages 5 to 12: $12.50
- Spectator parking: $12.50
- VIP admission: $75.47
- Show-car entry: $33.49, or $85.96 for VIP show-car entry
The two events run on different terms. The market costs nothing to enter or park at and closes at 1 p.m. Cars & Copters runs until 4 p.m. and charges for both admission and spectator parking. They overlap for three hours that morning on the same grounds.
The light show turns December evenings into ticketed nights
The second big event moves the grounds to evenings. Fiesta Shows' South Shore Celebration of Lights runs at the Marshfield Fairgrounds from Nov. 27 to Dec. 30, 2026. It's a drive-through display with more than a mile of roadway, more than one million LED lights, a 300-foot tunnel and animatronic scenes.
The light show uses a different entrance from the market. Its gate is Gate E, at 62 S. River St., not Gate A on the Main Street side.
The show doesn't run every night of its five-week season. It's open 30 of the 34 nights between Nov. 27 and Dec. 30. The dark nights are Monday, Nov. 30; Tuesday, Dec. 1; Monday, Dec. 7; and Tuesday, Dec. 8. Thursday, Dec. 31, falls outside the season. On every open night, entry is sold in hour-long sessions from 5 to 9 p.m., with last admission at 8:15.
Prices are per car and depend on the night and where you buy:
| Night type | Dates | Online, per car | On-site, per car |
|---|---|---|---|
| Weekday | Mondays Dec. 14, 21, 28; Tuesdays Dec. 15, 22, 29; Wednesdays Dec. 2, 9, 16, 23, 30; Thursdays Dec. 3, 10, 17 | $22.99 | $30 |
| Weekend and holiday | Fridays Nov. 27, Dec. 4, 11, 18; Saturdays Nov. 28, Dec. 5, 12, 19, 26; Sundays Nov. 29, Dec. 6, 13, 20, 27; Dec. 24 and 25 | $26.99 | $35 |
| Flex pass | Any open date and time | $30 |
Limousines, 12- and 15-passenger vans, and small buses pay $40 online or $50 at the gate on weekdays, and $50 or $60 on weekends and holidays.
A few numbers in that table matter more than the rest. The flex pass costs $30, which is $3.01 more than a dated weekend ticket bought online and $5 less than a weekend ticket at the gate. It's priced for flexibility, not savings. The gate itself isn't guaranteed either. Fiesta Shows says that if a night sells out online, no tickets will be sold at the gate.
The December market falls on Saturday, Dec. 19, which is also a weekend light-show night. That means one day with a grandstand market and Chris Carter playing from 10 to 1, then drive-through sessions starting at 5 p.m. through a different gate.
What fills the grounds between the dated events
The public calendar is short, but the grounds stay busy. The Society describes its mission as promoting education and development in agriculture, horticulture, the mechanical arts and related fields. It lists several year-round uses that never appear as public events:
- Community Christmas operations
- Training for local fire, police and sheriff's departments
- Beekeeper and garden-club meetings
- 4-H training
- Standby use as an emergency animal shelter in a disaster
None of these has a published date, and most aren't meant for drop-in visitors. They help explain why the grandstand sees regular use well before the August fair returns.
The posted calendar for the next eight months is simple. There's the market on Oct. 17, Nov. 21, Dec. 19, Jan. 16, Feb. 20, Mar. 20, Apr. 17 and May 15. Cars & Copters is on the first of those dates, and the light show's weekend nights include the third. The Fair's events page is the place to watch for anything added between now and May.
The third-Saturday market is one of the small routines that shapes a Marshfield winter, and those routines are part of what Poppy Troupe talks through with South Shore families every day.
