Costco shopping: avoiding crowds requires strategic timing

According to Simply Recipes, Sunday afternoons, specifically between 11 a.m. and 2 p.m., often represent the peak congestion period, though this can fluctuate by location. One Reddit user described a Sunday visit as “crazy,” while another recounted lengthy lines extending to the store’s rear.

Costco, based in Issaquah, Washington, was contacted for comment.

While midweek shopping presents challenges for those with standard work hours, Monday mornings may offer a more tranquil environment. However, shoppers prioritizing fully stocked shelves might find Tuesday or Wednesday to be ideal, as inventory is typically replenished during those days, as reported by Southern Living.

“In my experience, Tuesdays earlier in the day seem to be the best option,” a Reddit user shared. Another shopper advised avoiding Friday, Saturday, Sunday, and Monday. They suggested Tuesday, Wednesday, and Thursday as generally safer choices, particularly earlier in the day.

Many shoppers have found success by visiting during the first or last hour of operation on weekdays. “First hour or last hour seems to be the best times in general. … Going after 6:30pm on a weeknight seems to be the best for my Costco,” one person noted.

Costco’s revenue reached $297.3 billion in the 2025 fiscal year, a 10.2% increase from $269.9 billion the previous year.

The day before a holiday can also draw significant crowds, especially if Costco is closed on the holiday, according to The Takeout. Costco warehouses are generally open seven days a week, and specific operating hours and holiday closures can be found on the company’s website.
