April, July, August and October — French school holidays — Easter, the summer, and the Toussaint break.
Quietest months
March, June, September and November — term-time weekdays, when most experiences are near walk-on.
Local knowledge: Stay for the night show — the day is paced so the evening is the finale, and the last two hours before it are the emptiest of the day.
How this is worked out
Each day starts from how that weekday normally runs at Futuroscope, 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.
