July, August and October — the north-German summer holidays and the Halloween season.
Quietest months
April, May and September — spring and September weekdays, when the park often feels half-empty.
Local knowledge: Colossos first, Dämonen second, then work outward — the wooden giant's queue only grows all day.
When to avoid Heide Park, and when to go

Scores are the crowd forecast, 1 to 10, averaged over the stretch. *School holidays vary by district, state or zone; these are the typical dates, so check your own. 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 Heide Park, 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.
