Knowing the exact Costco Fairfax hours before you head out saves you from a wasted trip down the Fairfax County Parkway or Route 50. Warehouse schedules shift between weekdays and weekends, and specialty areas like the tire center, pharmacy, and gas station operate on independent timetables that don't match the main warehouse doors.
This guide breaks down the actual operating schedule for the Fairfax, Virginia location at 4725 West Ox Road, details holiday closures, exposes the best times to beat the crowds, and answers common scheduling questions.
Regular Costco Fairfax Operating Hours
The Fairfax warehouse follows standard regional scheduling for Costco locations in Northern Virginia, though weekday hours stretch slightly later than weekend evening closes.
- Monday through Friday: 10:00 AM to 8:30 PM
- Saturday: 9:30 AM to 6:00 PM
- Sunday: 10:00 AM to 6:00 PM (Note: Some regional warehouses open Sundays at 9:30 AM, but Fairfax strictly maintains 10:00 AM Sunday warehouse doors for general shopping.)
Weekday mornings right at opening tend to be calm, while weekday evenings between 5:00 PM and 7:00 PM bring a surge of commuters stopping by after work. Saturday mid-day is consistently the busiest window of the week, with parking lots filling up fast near the entrance.
Specialty Department Hours in Fairfax
The main warehouse doors tell only part of the story. If you're visiting for gas, prescriptions, or new tires, check these specific departmental schedules:
- Gas Station: Fuel pumps open earlier and close later than the warehouse. Usually, gas hours run from 6:00 AM to 9:30 PM Monday through Friday, 7:00 AM to 8:00 PM on Saturdays, and 7:00 AM to 7:00 PM on Sundays. Early morning and late evening are the smartest times to pull up without waiting in line.
- Pharmacy: The pharmacy operates on standard business hours, typically closing earlier on Saturdays and staying completely closed on Sundays. Expect weekday hours from 10:00 AM to 7:00 PM, Saturdays from 9:30 AM to 6:00 PM, and Sunday closures.
- Optical and Hearing Aid Centers: These counters generally mirror weekday and Saturday warehouse hours but close earlier on weekends or take a midday lunch break when staff is limited.
- Tire Service Center: Tire installation and rotation hours usually run Monday through Saturday from 10:00 AM to 6:00 PM, staying closed on Sundays.
Holiday Schedule and Closures
Costco closes its warehouse doors on major federal and cultural holidays so employees can spend time with family. If you plan to stock up for a holiday cookout or family gathering, note these standard closures:
- 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, the warehouse typically closes early—usually around 5:00 PM—so keep your afternoon schedule tight if you need last-minute items. For exact holiday announcements, check local store updates directly through the Costco Warehouse Finder.
Strategic Shopping Tips for the Fairfax Location
Navigating a busy suburban warehouse requires more than just knowing the hours. Use these practical strategies to make your trip efficient:
- Target the sweet spot: Arrive about 15 minutes before opening on weekdays to catch the initial wave, or shop during the final hour before closing when foot traffic drops significantly.
- Check gas lines first: If you approach from West Ox Road, glance at the fuel queue before parking. When the line spills past the first two islands, park your car and shop inside first—the fuel queue often clears out while you check out.
- Skip the food court bottleneck: The food court is busiest between 12:00 PM and 2:00 PM on weekends. If you want a hot dog or pizza, order at the kiosk immediately after paying for your cart items rather than waiting until you exit.
