Is Costco Open Today? Updated Store Hours & Holiday Schedule for Shoppers

Is Costco open on Memorial Day 2025? No. Costco warehouses nationwide will be closed on Monday, May 26, 2025 in observance of Memorial Day, one of seven U.S. holidays when the club retailer shuts its doors each year. Why Costco closes for Memorial Day Costco’s holiday-closure policy is designed to give employees time with family, reduce overhead on historically low-traffic holidays, and keep membership fees competitive. The chain’s full 2025 shutdown list includes: • New Year’s Day • Easter Sunday • Memorial Day (May 26) • Independence Day (July 4) • Labor Day (Sept 1) • Thanksgiving Day (Nov 27) • Christmas Day (Dec 25) What to do if you need bulk items on Memorial Day • Shop early: Most warehouses close at 8:30 p.m. Friday and open 9 a.m.–6 p.m. Saturday; hours vary Sunday. • Consider same-day delivery: Costco partners with Instacart in many ZIP codes; order by 3 p.m. Sunday for Monday delivery windows. • Check alternative retailers: Sam’s Club will operate limited hours (8 a.m.–6 p.m.) on Memorial Day, while Walmart and Target remain open with regular or slightly reduced hours. • Refuel in advance: Costco gas stations follow warehouse closures, so top off by Sunday evening. Regular Costco hours after the holiday All locations resume standard weekday operations—typically 10 a.m.–8:30 p.m.—on Tuesday, May 27. Pharmacy and optical departments reopen with normal in-store hours as well. Tips for avoiding post-holiday crowds 1. Arrive within the first hour on Tuesday. 2. Use the Costco app to preload your digital membership card for faster entry. 3. Target high-demand aisles (meat, produce, paper goods) first; restocking is heaviest early in the day. 4. Consider mid-week shopping (Wednesday or Thursday) for the calmest experience. Bottom line If you’re asking “Is Costco open today?” and today is Memorial Day 2025, the answer is no—but with a little planning you can still score your favorite bulk bargains before or after the holiday while enjoying more time for the long-weekend cookout.
