May, July, August and October — half-terms, the UK summer holiday, and Fright Nights in October.
Quietest months
April, June and September — term-time weekdays in spring and September.
Local knowledge: Thorpe is on an island site with a lot of water — wind closures on the tall rides are common enough to be worth a contingency plan.

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 Thorpe 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.
Want the live picture instead? Thorpe Park 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.
