- Peak season (July–August): Expect beautiful, long daylight hours and vibrant river activity. The open-air decks fill up instantly, and crowds are at their highest. Booking several days in advance is essential.
- Shoulder season (May–June & September): This is the ideal sweet spot. The weather is comfortably warm, the skies are generally clear for photography, and lines at the Willemsplein and Parkhaven docks are much shorter.
- Off-peak season (October–April): While crowds disappear and ticket availability is open, fewer sailings operate daily. Guests must remain inside the heated glass salons due to crisp, cold harbor winds.
