Seasonal closure: Sesame Place Philadelphia is typically closed in February, so those months don’t appear in the table. Exact operating dates vary by year — check the official park calendar before booking travel.

Months open fewer than 15 days (January) aren’t ranked above, so a short operating window can’t skew the month averages.
