This crowd calendar predicts daily crowd levels for Six Flags Great Adventure through 2026.What the % means

The number is how full the park is: how long the queues run on its main rides in the middle of the day, on one scale for every park (50% is about a 17-minute queue, 70% half an hour, 90% an hour), or, where the park sells dated tickets, the share of its capacity sold if that is higher. The word beside it (Quietest to Busiest) compares the day with this park's own history, so a small park can be at its busiest on a day that is still short queues. The lower the number, the shorter the queues, so pick a quiet day and ride more.
