Costco Will Be Closed on Monday- Here’s What Shoppers Need to Know

If you’re planning a Costco run on Monday, you’ll want to change your plans.

Costco warehouses across the U.S. will be closed on Monday, September 7, 2026, in observance of Labor Day.

That means shoppers will need to get their Costco run done before the holiday or wait until Tuesday.

Costco Is Closed on Labor Day

Labor Day is one of the major holidays when Costco closes its U.S. warehouses.

Since the holiday always falls on a Monday, it can be an easy closure to forget—especially if Monday is normally one of your regular Costco shopping days.

If you need groceries, drinks, grilling supplies, paper goods or other Labor Day weekend essentials, you’ll want to shop before Monday.

Expect a Busy Weekend at Costco

The days leading up to Labor Day can be busy at Costco as shoppers stock up for cookouts, parties and the long weekend.

If you’re planning to shop this weekend, going earlier in the day may help you avoid some of the crowds. I also wouldn’t wait until the last minute if there’s a specific seasonal or holiday item you want, since popular products can sell out.

When Will Costco Reopen?

Costco warehouses are expected to reopen on Tuesday, September 8, with regular warehouse hours.

Hours can vary by location, so it’s always a good idea to check your local Costco before heading out.

Costco Is Closed on Several Holidays Each Year

Labor Day isn’t the only holiday when Costco shuts its warehouse doors.

Costco also closes on several other major holidays throughout the year, including Thanksgiving, Christmas and New Year’s Day.

Plan Your Costco Run Before Monday

For this weekend, the key thing to remember is simple: Costco will be closed on Monday, September 7.

If you have anything you still need for the holiday weekend, try to get your shopping done before then so you don’t end up making a wasted trip.
