The heaviest pumpkin ever weighed at Half Moon Bay came in at two thousand seven hundred and forty-nine pounds. That is a tonne and a quarter of squash, grown in a single season, in a garden, by a person with a job. The world of competitive giant pumpkin growing is small, obsessive, quietly technical, and once a year it converges on a stretch of the San Mateo coast.
The strangest events in the Bay Area happen on weekday mornings and cost nothing to watch. Tell Karpo what is on near you and get the ones that are actually worth taking a morning off for.
It is a Monday morning, and it is free
The Safeway World Championship Pumpkin Weigh-Off opens the Half Moon Bay pumpkin season on the Monday before the festival weekend, on the IDES Grounds. Growers arrive from across North America with their pumpkins strapped to flatbed trucks and trailers, and they are lifted off one at a time by forklift onto a scale.
The format is the appeal. There is no build-up, no staging and no attempt to make it televisual: a fruit is lifted, a number appears, and a small crowd of people who understand exactly what that number means react accordingly. It takes a few hours, it happens on a weekday morning, and watching costs nothing.
The money is serious
First place is paid nine dollars per pound, which is the largest prize of its kind anywhere. At the weights these growers reach, that is a five-figure cheque for a vegetable — a two-thousand-three-hundred-pound pumpkin, the sort of weight that has recently won here, pays out over twenty thousand dollars.
On top of that there is a thirty-thousand-dollar bonus for breaking the world record. That single line explains the atmosphere better than anything else: every grower who arrives with something over two and a half thousand pounds is arriving with a genuine shot at it, and everybody present knows the current mark to the pound.
- Held on the Monday before the Half Moon Bay Art & Pumpkin Festival, on the IDES Grounds
- Free to watch; the weighing runs through the morning
- First place is paid $9 per pound — the biggest prize of its kind
- A $30,000 bonus is on offer for a new world record
- The record stands at 2,749 pounds, set at Half Moon Bay in 2023
It is worth understanding why the prize is structured per pound rather than as a flat purse. Paying by weight means there is no ceiling and no reason to stop pushing once you know you have won — a grower who has the heaviest pumpkin on the grounds is still being paid for every additional pound, which is precisely the incentive that has driven the record up by hundreds of pounds over the last two decades. The prize structure is, in a real sense, the reason the sport keeps escalating.
What you are actually looking at
Competitive giant pumpkins are a specific variety, Atlantic Giant, and they do not look like the thing on your doorstep. At this size they are pale orange to almost white, flattened by their own weight, ribbed and split-skinned, and closer to a geological formation than a vegetable. A pumpkin at peak growth can put on more than forty pounds in a day, which is a rate of growth you can genuinely observe.
The growers are the other half of it. This is a hobby that involves soil chemistry, controlled pollination, pedigree seed lines traded between a few hundred people worldwide, and a season that starts in April and ends with a forklift. Most of them are entirely happy to explain all of it if you ask, and the explanations are more interesting than the weights.
There is a second act, too. The winning pumpkin does not go home — the largest entries are displayed in town through the festival weekend, and several end up carved by professional sculptors into something considerably more elaborate than a face. If you cannot make the Monday, the pumpkins themselves are still on the coast the following weekend, minus the forklift and the tension.
Getting there and making a morning of it
Half Moon Bay is about forty-five minutes from San Francisco over Highway 92 or down the coast on Highway 1, and the coast road is the better choice if the fog has lifted. Because the weigh-off is on a weekday morning, the traffic that ruins the festival weekend is not a factor — this is the easy visit, not the hard one.
Get there for the start. The largest entries tend to be weighed later in the proceedings, but the early part is where you can walk among the trucks, look at the pumpkins at close range and talk to growers before anyone is preoccupied. By the time the leaders come off the trailers, the crowd around the scale is several deep.
Afterwards the whole coastside is open on a Monday: the pumpkin farms along Highway 92 without the weekend queues, the beach at Poplar or Dunes, the harbour at Pillar Point for lunch, and the bakeries in town. A weigh-off in the morning and fish at the harbour at one o'clock is a better day than the festival weekend offers, and it involves roughly a tenth of the people.
Bring a coat regardless of what the forecast in the city says. Half Moon Bay sits directly on the water and October mornings there are frequently grey, damp and ten degrees cooler than San Francisco, and the grounds are open with nothing to stand behind.
Practical notes
The Safeway World Championship Pumpkin Weigh-Off takes place on the IDES Grounds in Half Moon Bay on the Monday before the Art & Pumpkin Festival weekend, in mid-October. It is free to watch and runs through the morning. First place is paid nine dollars per pound, with a thirty-thousand-dollar bonus for a world record; the record of 2,749 pounds was set here in 2023, and recent winners have come in above 2,300. Allow forty-five minutes from San Francisco, arrive at the start to see the pumpkins up close, and use the rest of the weekday to visit the coastside without the festival crowds.
