Costco Hours 2026 — Opening Times, Holiday Hours and Best Times to Go

Standard Costco Hours 2026

The vast majority of US Costco warehouses follow the same standard weekly schedule. These are the regular Costco hours that apply on non-holiday weeks at most locations:

Costco Holiday Hours 2026

Costco closes completely on six holidays every year and operates on reduced hours on several others. These are the most important Costco holiday hours to know for 2026:

Executive Member Early Access Hours

Executive members at most US Costco locations get access to the warehouse one hour before regular members on weekdays. This means Executive members can enter at 9:00am Monday through Friday while Gold Star members must wait until 10:00am.

This early access hour is one of the most underused Executive membership benefits. The warehouse is significantly quieter during the first hour of opening — checkout lines are shorter, parking is easier, and popular items that sell out by midday are fully stocked. For members who shop frequently, the early access hour alone can justify the membership upgrade if time efficiency matters.

Best and Worst Times to Visit Costco

Knowing Costco hours is one thing — knowing when to actually go is another. Costco is one of the most heavily trafficked retailers in the US and the difference between a 20-minute shop and a 90-minute ordeal is almost entirely determined by when you arrive.

How to Check Your Local Costco Hours

While the standard hours above apply to most US warehouses, individual locations can vary — particularly in urban areas, airports, or business centres that operate on different schedules. There are three reliable ways to check your specific warehouse hours.

The Costco app shows live hours for your nearest warehouse including any temporary changes or holiday adjustments. The warehouse finder on costco.com lets you search by zip code and shows current hours, departments and services. Google Maps also updates Costco hours reliably and will show reduced or holiday hours when they apply — searching "Costco near me" will surface current hours without needing the app.

Costco Gas Station Hours

Costco gas station hours are different from warehouse hours and vary more significantly by location. In general, Costco gas stations open earlier and close later than the main warehouse, but this is not universal. A typical gas station schedule runs 6:00am to 9:30pm on weekdays and 6:00am to 8:00pm on weekends, but you should verify this for your specific location.

Gas stations at Costco are closed on the same holidays as the main warehouse. On reduced-hours holidays the gas station typically follows the warehouse schedule. The most reliable way to confirm gas station hours is through the Costco app warehouse finder which lists gas station hours separately from main warehouse hours.

Can You Enter Costco Without a Membership?

Costco is a members-only warehouse and requires a valid membership card or a Costco Shop Card (gift card) to enter. The membership check happens at the entrance and staff are consistent about enforcing it. You cannot enter by telling them you are browsing or accompanying a member — each adult in your party needs a membership card or you need a gift card to cover the group.

The gift card entry route is the most practical option for anyone who wants to visit Costco without a membership. Gift card holders get full warehouse access including all departments, the food court and the gas station. There is no minimum spend and the card balance carries over between visits.
