How the Six Flags Great Adventure crowd figures are worked out
Every figure on this page comes from queue times recorded at Six Flags Great Adventure itself, sampled every few minutes across every ride the park publishes and stored day by day. A day's crowd score is that day's average wait expressed against this park's own busiest recorded day, so 100% means "as bad as it gets here" rather than "as bad as it gets anywhere" - a quiet day at a small park and a quiet day at Six Flags Great Adventure are not the same number of minutes, and scoring each park against itself is the only way the months stay comparable. In plain minutes, the park-wide average across the last 59 operating days runs from 19 minutes at its calmest hour to 25 minutes at 11am. Months with fewer than 10 recorded operating days are left unranked rather than averaged from a handful of days, and holidays, school terms and weather are all part of the model.
We publish how well those forecasts actually hold up: the crowd forecast accuracy ledger scores every past prediction against what the queues did on the day, versioned so you can see whether the model is getting better or worse. If you are choosing between parks rather than dates, the best time to visit a theme park guide covers the seasonal patterns that hold across every park we track, and the Six Flags Great Adventure crowd calendar gives you a day-by-day forecast for the specific dates you are considering. Always check the park's own site for opening hours and closures before travelling.
