Verified September 29, 2026. October in New York City creates a useful choice: you can prioritize peak fall produce, hunt for vintage and handmade goods, or visit a farm-based market where shopping is part of a larger harvest-season outing. The trade-off is that these markets do not operate under one shared schedule or weather policy. Some are year-round, some are seasonal, some require sellers to qualify as producers, and one limited fall pop-up ends during the first week of October.
This guide includes only markets and sales whose October 2026 schedule could be verified on the organizer’s own website or a New York City source. It does not list unconfirmed social-media pop-ups, third-party event calendars, or markets whose 2026 dates were not published.
| Market | October 2026 dates | Hours | Best fit | Season status |
|---|---|---|---|---|
| Union Square Greenmarket | Oct. 2, 3, 5, 7, 9, 10, 12, 14, 16, 17, 19, 21, 23, 24, 26, 28, 30, 31 | 8 a.m.–6 p.m. | Largest choice of regional farm products and multiple weekly shopping days | Year-round |
| Tribeca Greenmarket | Oct. 3, 10, 17, 24, 31 | 8 a.m.–2 p.m. | A compact Saturday produce stop in Lower Manhattan | Year-round |
| City Hall Greenmarket | Oct. 6, 13, 20, 27 | 8 a.m.–4 p.m. | Tuesday shopping near the Civic Center | Season ends Nov. 24, 2026 |
| Bowling Green Greenmarket | Oct. 6, 13, 20, 27 | 8 a.m.–3 p.m. | Tuesday produce shopping in the Financial District | Season ends Nov. 24, 2026 |
| Grand Bazaar NYC | Oct. 4, 11, 18, 25 | 10 a.m.–5 p.m. | Vintage, design, art, fashion, handmade goods and food vendors | Year-round Sundays |
| A Taste of Grand Bazaar at Hudson Square | Oct. 7 | 11 a.m.–6 p.m. | A weekday downtown pop-up | Final date of the fall series: Oct. 7 |
| Queens County Farm Museum Farmstand | Wed.–Sun.: Oct. 1–4, 7–11, 14–18, 21–25, 28–31 | 10 a.m.–4 p.m. | Farm-grown produce plus a harvest-season farm visit | Season ends Nov. 25, 2026 |
Address: Union Square, with market space on 17th Street between Broadway and Park Avenue South and on Union Square West between 17th and 15th Streets.
GrowNYC lists Union Square Greenmarket as a year-round market open Monday, Wednesday, Friday and Saturday from 8 a.m. to 6 p.m. That produces 18 verified October 2026 shopping dates: October 2, 3, 5, 7, 9, 10, 12, 14, 16, 17, 19, 21, 23, 24, 26, 28, 30 and 31. See the official Union Square Greenmarket page.
Admission: There is no admission ticket; it is a public farmers market. Seller registration: this is not a casual flea-market setup. GrowNYC operates Greenmarket as a producer-only program. Farmers and eligible food producers must apply and meet regional and product requirements through the GrowNYC Greenmarket program.
Weather trade-off: do not assume “rain or shine.” GrowNYC closed Union Square Greenmarket on September 26, 2026 because of inclement weather and posted the closure on the market page. For an October day with a severe forecast, check that same official page before traveling.
Transit: the 14 St–Union Sq subway complex is the obvious transit hub. MTA maps show service by the 4, 5, 6, L, N, Q, R and W routes. Weekend service can change, so verify the trip on MTA’s official site.
Address: Greenwich Street between Chambers and Duane Streets, Manhattan.
Tribeca Greenmarket is open every Saturday year-round from 8 a.m. to 2 p.m., so its October dates are October 3, 10, 17, 24 and 31. GrowNYC also lists a Saturday clothing collection from 8:30 a.m. to 1:30 p.m. See the official Tribeca Greenmarket listing.
The main advantage over Union Square is scale and timing: Tribeca is easier to combine with a Lower Manhattan morning, but it closes four hours earlier. Admission is free. Seller eligibility follows the same GrowNYC producer-only application rules rather than first-come flea-market booth rental.
Weather: GrowNYC also closed Tribeca Greenmarket on September 26, 2026 for inclement weather. That recent example confirms that weather can cancel a scheduled day. Check the live market page on the morning of your visit.
Transit: Chambers Street subway stations serve the area; exact routing depends on your origin and planned service changes. Use the official MTA trip planner rather than assuming a normal weekend schedule.
These two seasonal GrowNYC markets run on the same Tuesdays in October—October 6, 13, 20 and 27—but suit different itineraries.
Address: Broadway between Chambers and Warren Streets. Hours: 8 a.m.–4 p.m. The verified 2026 season runs from May 5 through November 24. Official details: City Hall Greenmarket.
Address: Broadway and Battery Place. Hours: 8 a.m.–3 p.m. Its 2026 season also runs from May 5 through November 24. Official details: Bowling Green Greenmarket.
Choose City Hall if you want a later closing time or are already near the Civic Center and Tribeca. Choose Bowling Green if your day is centered on the Battery or Financial District. Both are public markets without admission charges, and both use GrowNYC’s producer application rather than casual seller registration.
Weather: GrowNYC does not publish a blanket promise that every market opens in all weather. Because its market pages are used for real-time closure alerts, check the individual location page when conditions are hazardous.
Address: 100 West 77th Street at Columbus Avenue, Manhattan. Hours: every Sunday, 10 a.m.–5 p.m., indoors and outdoors. Admission: free and open to all ages.
The organizer has published four themed October 2026 Sundays:
These dates are listed on the Grand Bazaar NYC official events page. Unlike seasonal produce markets, Grand Bazaar operates year-round, so October 25 is not its final market date.
Seller registration: merchants must apply first. Approved vendors then request available dates; the organizer says bookings are generally released about three months before an event, with payment required to confirm a space. October 2026 also brings new booth fees effective October 1. Use the official vendor information page rather than assuming a walk-up table is available.
Weather: Grand Bazaar states that it operates year-round, rain or shine, unless major weather or unsafe conditions intervene. Its vendor FAQ says weather-related refunds are not offered. This is a meaningful difference from GrowNYC markets, which can post full weather closures.
Transit: the organizer lists the C train at 81st Street or 72nd Street, the 1 at 79th Street, and the 1/2/3 at 72nd Street, plus several bus routes including M7, M11, M79 and M104. See the official transportation page and recheck MTA service status before leaving.
A Taste of Grand Bazaar at Hudson Square is the most time-sensitive listing in this guide. The final date of its four-Wednesday fall series is Wednesday, October 7, 2026, from 11 a.m. to 6 p.m. The organizer describes the location as the new Hudson Square Plaza between Spring and Dominick Streets. The market includes food, vintage finds, fashion, accessories and art. See the official October 7 event page.
The event listing provides an RSVP option but does not state an admission charge. Because this is a curated Grand Bazaar series rather than an open neighborhood stoop sale, prospective sellers should use Grand Bazaar’s vendor application process. For transit, use the MTA trip planner with Hudson Square Plaza as the destination because subway service changes can affect the best route.
Address: 73-50 Little Neck Parkway, Floral Park, Queens, NY 11004. The seasonal Farmstand runs Wednesday through Sunday, 10 a.m.–4 p.m., from May 13 through November 25, 2026. In October that means October 1–4, 7–11, 14–18, 21–25 and 28–31. See the official Farmstand page.
This choice differs from a conventional multi-vendor farmers market: the stand sells Queens Farm produce and selected items from partner New York farms. The official site does not advertise casual seller registration for the Farmstand, so it should not be treated as an open vendor market.
Admission: Queens Farm grounds are generally free for individual visitors, but special ticketed event days are exceptions. In October 2026, for example, the farm has ticketed events including the Agricultural Fair on October 3–4 and Halloween on the Farm on October 31, so check the day’s event listing before assuming ordinary free access. The official visitor page explains the admission rule.
Weather: the Farmstand page notes that product availability varies with seasonality and weather, but it does not publish a blanket Farmstand rain-cancellation rule. If the forecast is severe, check the farm’s event and visitor pages or contact the farm before traveling.
Transit: Queens Farm’s official site lists the Q46, QM6 and Q36 buses. This is the least subway-oriented option in the guide, so allow more travel time than for the Manhattan markets.
The largest trade-off for sellers is eligibility versus flexibility. GrowNYC Greenmarkets are producer-only: they are designed primarily for regional farmers and narrowly defined food producers, not vintage dealers or general crafts vendors. Grand Bazaar is better suited to vintage, handmade, art, fashion and specialty-food sellers, but approval does not guarantee every requested Sunday because the organizer curates its mix and has limited space.
Queens County Farm Museum’s Farmstand is not presented as an open vendor marketplace, so there is no verified public booth-registration route to recommend. For the Hudson Square pop-up, use the Grand Bazaar application system rather than treating the plaza as a day-of community vending site.
October weather can change quickly, and the organizers take different approaches:
If your priority is maximum produce variety and schedule flexibility, Union Square gives you four market days most weeks. If you want a quieter Saturday produce stop, Tribeca is a simpler two-hour-to-half-day pairing with Lower Manhattan. City Hall and Bowling Green work well for Tuesday office-district visits, with City Hall staying open one hour later.
For vintage and handmade shopping, Grand Bazaar is the clearest verified October option because every Sunday has a published 2026 theme and free public admission. If you want something more limited and weekday-friendly, October 7 at Hudson Square is the final chance for that fall pop-up series. For families who want produce shopping combined with an actual working-farm setting, Queens Farm offers the most distinctive experience, but transit takes longer and special-event admission can alter the normal free-entry pattern.
Use the organizer link on the morning of your visit, especially after heavy rain or a storm warning. Confirm the date, closing time and any special-event ticket requirement; then check MTA service changes. Sellers should confirm approval and booking rather than arriving with merchandise. That last step matters because the markets in this guide range from strict producer-only programs to curated flea and maker bazaars, and none should be assumed to accept unscheduled vendors.
