Costco warehouses get crowded, but shopping at specific times can help you avoid the rush.

Weekends draw heavy traffic since most people are off work. Shop midweek instead, on Tuesday or Wednesday. On weekdays, aim for early afternoon around 1 p.m., after the lunch crowd leaves but before the after-work rush starts. Plan to leave by 3 p.m. to also dodge rush hour traffic.

Avoid shopping between 4 and 7 p.m. on weekdays when commuters stop by on their way home. Costco closes at 8:30 p.m. on weekdays, leaving little time if you arrive later in the evening.

Time your visits to avoid new discount cycles, which draw extra shoppers. Skip the periods right before major holidays like Thanksgiving and July 4, when people stock up heavily.

Costco Executive members pay a $130 annual fee instead of the standard $65 and get early entry to the store before other shoppers. This works best if you wake up early.

Rainy weather and major televised events like the Super Bowl thin out crowds considerably. Fewer people shop during bad weather or when big games are on.

Each Costco location has different traffic patterns. Building a routine around the quieter times at your specific warehouse will improve your shopping experience.
