The months that actually matter at Six Flags St. Louis
Busiest months
June, July, August and October — the summer holiday and Fright Fest weekends.
Quietest months
May and September — May and September weekdays.
Local knowledge: Missouri humidity peaks mid-afternoon; the water rides here are a genuine part of the plan rather than an afterthought.

Scores are the crowd forecast, 1 to 10, averaged over the stretch. Visiting in a busy stretch anyway? Be at the gate before opening, and ride the big ones in the first hour and the last.
How this is worked out
Each day starts from how that weekday normally runs at Six Flags St. Louis, learned from our own recorded wait snapshots as they accumulate, and is raised for public holidays and school-holiday periods. It is a forecast of relative busyness, not a promise: a 3 means a day that usually runs quiet for this park, not a guarantee of short lines. The further out a date sits, the more it leans on the weekday pattern alone.
Want the live picture instead? Six Flags St. Louis wait times has today's queues, the hour-by-hour curve and what counts as a normal wait here. Planning a specific day? Open the planner and it will build a route around these crowd levels.
