Most standard Costco warehouses close at 8:30 PM Monday through Friday, and at 6:00 PM on Saturdays and Sundays. However, operating hours vary slightly depending on your specific region, local zoning laws, and whether you are visiting an auxiliary department like the gas station, pharmacy, or a Costco Business Center. Knowing the exact closing schedule saves you from rushing through the aisles or arriving to locked doors.
Understanding how warehouse schedules shift during weekends, holidays, and special service hours helps you plan your bulk shopping trips efficiently. Whether you need to pick up groceries after work or fill your tank late in the evening, checking the distinct schedules for each department prevents wasted trips.
Standard Costco Warehouse Closing Times
The core warehouse locations follow a reliable routine across North America, though minor regional discrepancies do occur.
- Monday through Friday: Stores typically open at 10:00 AM and close at 8:30 PM.
- Saturday: Warehouses open earlier at 9:30 AM and close earlier at 6:00 PM.
- Sunday: Locations open at 10:00 AM and close at 6:00 PM.
Weekday evenings give you the longest window to shop after standard work hours, while weekends require an earlier arrival due to the shorter afternoon hours. Keep in mind that entry doors usually lock right at closing time, and registers close shortly after. Shoppers still inside when the doors lock are given a few minutes to check out, but lingering is discouraged.
Department Closing Times vs. Main Warehouse Hours
Auxiliary services inside and outside the warehouse rarely match the main building's closing schedule. If you plan to visit the pharmacy, tire service center, or gas station, check their individual timetables before heading out.
Costco Gas Station Hours
Gas stations generally open much earlier and close later than the main warehouse. Most locations keep fuel pumps open from 6:00 AM to 9:30 PM on weekdays, with shorter hours on weekends (usually closing around 7:00 PM). This setup allows members to fuel up before work or long after the warehouse closes its doors.
Pharmacy and Optical Center Hours
Pharmacies operate on traditional medical office hours. Most close by 6:00 PM or 7:00 PM on weekdays and often close earlier on Saturdays, while remaining closed on Sundays. If you need to pick up a prescription, don't assume you can grab it right before the main warehouse closes at 8:30 PM.
Food Court and Tire Service
Food courts generally stay open as long as the warehouse doors are open, though hot food prep winds down about 15 to 30 minutes before closing. Tire service centers usually close earlier in the evening and remain closed on Sundays entirely in many regions.
Costco Holiday Closures and Early Dismissals
Costco closes completely on several major holidays throughout the year. Planning your bulk grocery runs around these dates prevents unnecessary trips.
- New Year's Day: Closed
- Easter Sunday: Closed
- Memorial Day: Closed
- Independence Day (July 4th): Closed
- Labor Day: Closed
- Thanksgiving Day: Closed
- Christmas Day: Closed
On Christmas Eve and New Year's Eve, warehouses remain open but implement early closures, typically shutting their doors by 6:00 PM to let employees celebrate. You can verify active schedules directly through the official Costco Warehouse Locator.
Smart Shopping Tips to Beat the Closing Rush
Arriving an hour before closing might seem like a smart way to dodge crowds, but you run the risk of running out of time in a massive warehouse.
- Shop weekday mornings or late evenings: If you prefer empty aisles, aim for the final hour between 7:30 PM and 8:30 PM on a Tuesday or Wednesday. Foot traffic drops significantly during this window.
- Avoid Sunday afternoons: Sundays between 1:00 PM and 4:00 PM represent peak congestion times across almost all locations.
- Check local variations: State laws, province regulations, and local ordinances can force specific stores to close earlier on Sundays or alter alcohol sales cut-offs. Always confirm local details using the Costco Customer Service portal.
Frequently Asked Questions
What happens if I am inside when Costco closes?
Registers stop taking new customers shortly after the closing hour. Staff will gently herd remaining shoppers toward the front checkout lanes, so it is best to finish shopping at least 15 minutes prior to closing time.
Are Costco Business Center hours different?
Yes. Costco Business Centers cater to commercial shoppers and generally operate from 7:00 AM to 6:00 PM Monday through Friday, and 7:00 AM to 4:00 PM on Saturdays, while remaining closed on Sundays.
Do holiday closures apply to gas stations?
Most Costco gas stations close on major holidays like Thanksgiving and Christmas right alongside the main warehouse, though automated pumps may occasionally follow independent local schedules.
Can non-members shop during late hours?
Costco requires a valid membership card to make purchases at any time, though non-members can occasionally enter with a member if they aren't purchasing items or if they are using a Costco Shop Card.
