Downtown Hamilton is about to be overrun with pumpkins the size of small cars. The city's 15th annual Operation Pumpkin festival returns October 9 through October 11, lining the streets with giant sculpted pumpkins and hosting a weigh-off that has, in recent years, produced state records and drawn growers from well outside Ohio.
A Free Weigh-Off With Real Stakes
According to WLWT, the weigh-off kicks off at 5 p.m. on October 9, comes with no entry fee, and will award thousands of dollars in prize money to competing growers. That purse is part of a bigger pot: the Great Pumpkin Commonwealth-certified competition offers $35,000 in total prize money each year, along with custom championship belts and belt buckles, according to the Great Pumpkin Commonwealth. That kind of money is a big reason serious giant-pumpkin growers treat Hamilton as a destination rather than a local curiosity.
The payoff was on full display last October, when grower Jared Persinger set a new Ohio state record at the festival with a 2,505-pound giant pumpkin, according to the Scioto Post. Persinger's pumpkin actually finished second overall, behind a 2,518-pound entry brought by New York grower Scott Andrusz, but it still broke Ohio's previous record by more than 100 pounds. That old record, 2,388.5 pounds, had been set just the year before at the Circleville Pumpkin Show by growers Bob and Jo Liggett, per the same report.
Out-of-State Growers Keep Showing Up
The pattern isn't new. Back in 2022, grower Frank Morse set an Operation Pumpkin site record with a 2,350-pound pumpkin that also stood as a state record for Michigan, according to festival organizers at Operation Pumpkin. That same year, the festival included a weigh-off. The event has been the official sanctioned weigh-off site for the Southern Ohio Giant Pumpkin Growers since 2013, a club that was originally formed around 1999 after members drew inspiration from the Circleville Pumpkin Show, according to the group's own account of its history.
Hamilton's pumpkin pedigree stretches back even further into oddity. At the 2013 festival, Tennessee grower Chris Kent set the Guinness World Record for heaviest watermelon at 350.5 pounds, a fruit that reportedly contained roughly 1,500 seeds, according to Guinness World Records. It's a reminder that the festival's record-chasing reputation didn't start with pumpkins.
What's Happening Beyond the Scale
Weigh-off aside, most of what visitors will see this year are the sculpted pumpkins themselves. Per WLWT, giant sculpted pumpkins will line the streets of downtown Hamilton, with live carving happening in public on Friday and Saturday. The festival runs 11 a.m. to 10 p.m. on Friday and Saturday, and 11 a.m. to 5 p.m. on Sunday, with full details available at operation-pumpkin.org.
There's plenty for families beyond the carved gourds and the scale. For 2025, Ohio Magazine listed a Pet Parade and the Lil' Miss Punkin Contest, alongside more than 100 arts, crafts, and food vendors.
A Bigger Piece of Hamilton's Downtown Strategy
City officials treat the festival as more than a one-weekend party. Municipal budget reports from the City of Hamilton identify Operation Pumpkin alongside the RiversEdge Summer Concert Series as major downtown attractions that together draw over 100,000 total annual visitors and support local business growth, part of a broader civic push the city has described as a “city as a lab” strategy for revitalizing its urban core.
Circleville's Pumpkin Show, running since 1903 in Pickaway County, draws more than 400,000 visitors annually, according to Only In Your State. Hamilton's festival, by contrast, is a newer 21st-century tradition with an official Great Pumpkin Commonwealth weigh-off site. For Southwest Ohio, it offers a local giant-pumpkin event. At the 2025 festival, a pumpkin weighed 2,505 pounds.
