Costco shoppers hoping for a quick trip have a window to steer clear of: Sunday from 11 a.m. to 2 p.m. That three-hour stretch may be the worst time of the week to visit the warehouse club, Simply Recipes reported, according to a Nov. 1 roundup from Fox News Digital that also gathered crowd stories from shoppers on Reddit.
The timing is shopper-reported, not an official Costco figure, and crowd patterns can differ from one warehouse to the next. Fox News Digital said it reached out to Costco, which is headquartered in Issaquah, Washington, for comment, and the article did not include a response.
Why Sunday Midday Draws the Biggest Crowds
The Sunday stretch lands where weekend errands pile up. Weekends are busy because people are off work and stocking up for the week ahead, Fox News Digital reported in its Nov. 1 story on Costco crowd timing. The Sunday block from late morning to early afternoon is when that weekend stock-up traffic peaks, according to the Simply Recipes timing Fox cited.
The shopper accounts in the Fox roundup were blunt. One Reddit user described stopping by on a Sunday afternoon just to see what it was like, calling the scene “crazy” and adding, “Never doing that again.” Another said a Sunday trip had taught a hard lesson, recalling a checkout line that stretched all the way to the back of the store.
Those lines matter for households that shop in bulk. A full cart of paper goods, frozen proteins and pantry staples takes longer to ring up than a basket, so a backed-up front end can add real time to a trip. Shoppers who buy big also need somewhere to put it all, and these storage hacks for squeezing more out of every inch of space help when oversized packs of paper goods and cases of canned food come home at once, and this list of items worth keeping in the refrigerator at all times helps sort what goes on the cold shelves.
The Quieter Windows Shoppers Point To
Monday may be calmer because of smaller crowds, Fox News Digital noted, while Tuesday or Wednesday may be the better bet for fully stocked shelves since restocking is most likely done by then, a point the outlet credited to Southern Living. Midweek trips are harder for anyone working a 9 a.m. to 5 p.m. schedule, Monday through Friday, the article added.
Reddit users quoted by Fox leaned the same direction. One shopper who said they had lived across the country said Tuesdays earlier in the day seemed to be the best option, advised skipping Friday through Monday entirely, and called Tuesday through Thursday “generally safe bets, especially earlier in the day.” Another said the first or last hour of the day worked best, and that going after 6:30 p.m. on a weeknight had paid off at their store.
Food site The Takeout, in a Dec. 22, 2025, guide to the worst days and times to shop at Costco, pointed to the same midweek sweet spot, saying mid-morning to early afternoon from Tuesday to Thursday is the most predictable quiet window. The Takeout also flagged weekday evenings from roughly 4 p.m. to 7 p.m. as an after-work rush, and said Mondays can be busy all day because they are often restocking days. It suggested checking the Popular Times graph on Google Maps for a specific warehouse before heading out.
Planning the list before choosing the hour helps, too. Bulk shopping pays off most on staples that get used up, and the pantry classics in this look at budget foods that even wealthy households still buy are the kind of items that make a warehouse membership earn its keep.
Weekend trips also tend to stack several errands into one outing. Shoppers making extra stops can review these items never to leave in sight in a parked car during holiday shopping, and the planning habits in this piece on people who finish holiday shopping before Thanksgiving line up neatly with dodging the busiest hours.
Early Hours, Holidays and the Day After a Closure
Executive members get a head start. The Takeout described the 9 a.m. to 10 a.m. early-shopping slots for those members as exceptionally quiet. The Executive tier costs $130 a year after Costco raised the fee from $120 in September 2024, a change that affected 52 million members, according to Costco’s Wikipedia entry, which also lists 924 locations in 2026 and 145.2 million members in 2025.
Holidays scramble the usual pattern. The day before a holiday often brings heavy volume, especially when the warehouse will be closed for that holiday, Fox News Digital reported, citing The Takeout. The Takeout added that stores tend to be very busy the day after a closure, listing the days after New Year’s, Easter, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas. With Thanksgiving falling on Thursday, Nov. 26, this year, the Wednesday before and the Friday after fit the pattern The Takeout describes.
Costco warehouses are generally open seven days a week for members, and hours and closures vary by location. Members can look up a local warehouse’s hours and upcoming holiday closures on Costco’s hours and holiday closures page before planning a pre-holiday run.
Getting a Big Haul Home in Good Shape
A long wait at checkout adds minutes for refrigerated and frozen items sitting in the cart. The U.S. Department of Agriculture’s Food Safety and Inspection Service says perishable food should never be left out of refrigeration for more than 2 hours, or more than 1 hour when the temperature is above 90 degrees Fahrenheit. The agency calls the range between 40 and 140 degrees the “Danger Zone.”
That makes it sensible to grab cold and frozen items last, bag them together and head straight home on a busy day. Clearing shelf space in the refrigerator and freezer before the trip also shortens the time bulk packs spend on the counter.
For shoppers who can only go on weekends, the reported pattern still offers a workaround: arriving right at opening on Saturday or Sunday, or waiting until late afternoon after the midday rush, avoids the stretch from 11 a.m. to 2 p.m. that Simply Recipes and Reddit shoppers singled out.
