The average wait time depends on the season and day:
- April to September (high season): 30 to 60 minutes at the main entrance, especially between 10am to 1pm.
- October to March (low season): 15 to 25 minutes on weekdays. Expect longer queues on weekends and holidays.
- Weekends and public holidays: Always expect longer lines. It is best avoided with skip-the-line access.
- Special Klimt exhibitions or events: Wait times can spike by 30–45 minutes without prior booking.
