FAQ: Disney California Adventure crowds
How busy is Disney California Adventure in September 2027?
Each day below is scored 1 (lightest) to 10 (busiest) by comparing that day's park-wide median standby wait against every Disney California Adventure day we have on record. The scores come from wait times we sample every minute, not survey guesses.
Where does this crowd data come from?
Mickey Alerts records standby wait times at every Disneyland Resort attraction every minute, around the clock. A day's crowd score ranks its park-wide median wait, then its average wait, against every day in the park's full history on a 1–10 scale — the same data that powers our park planner's predictions. Scoring revision 2026-10-tie-aware (October 2026): each day is ranked by its park-wide median standby wait, then its average wait, against every day that park has on record, and tied days share one mid-rank level — so a repeated wait value never pins a whole stretch of days to a 1.
What do the projected days mean?
Days Disney has not yet reached (or rare gaps in our data) are projected from the same weekday at the same point in the season across prior years. Projected days are marked; observed days use the actual recorded waits.
How do I avoid the crowds once I pick a day?
Our park planner is free to use without signing in: machine-learning wait-time and Lightning Lane predictions trained on three years of this minute-by-minute data, plus the optimizer that orders your day for the least walking and the shortest lines.
