For 2026, the least busy days at Universal Studios Hollywood are consistently Tuesdays and Wednesdays. These mid-week days see a significant drop in attendance as the weekend "drive-in" crowd from the surrounding Southern California area returns to work and school. During the "off-peak" seasons—specifically the first week of March, the second half of April, and mid-week in September—wait times for major attractions like Super Nintendo World can be significantly lower. However, it is vital to check the calendar for "Fan Fest Nights" or "Halloween Horror Nights," as these special events can cause the park to close early or bring in larger crowds starting in the mid-afternoon. If you visit on a Tuesday in a "slow" month like February or October, you can often experience most of the park's top-tier attractions with minimal waits, whereas Saturdays and Sundays frequently see the park reach capacity with wait times exceeding two hours for the most popular rides.
