Cruise capacity by port and month
Port Day joins the published schedules of 37 cruise lines into one count per port, by week and by month: how many ships call, and how many berths they bring. It is built for excursion marketplaces deciding where to add operators, and for destination teams watching the ports they compete with.
A tour operator in Juneau knows when the ships dock in Juneau. A marketplace with operators in forty ports has a harder question: where to recruit next season, and where it already has more supply than passengers.
The answer is spread across dozens of cruise lines, each publishing only its own ships. Booking systems carry the lines they sell, one sailing at a time. Port Day adds every line together, port by port and week by week, up to four years out.
Sample
Scheduled berths per month at the four busiest Inside Passage ports. Every number below is already on a cruise line's published schedule.
1.57M berths
1.70M berths
1.36M berths
0.62M berths
A berth here is a lower berth: two beds per cabin, the industry's standard measure of capacity. Ships often sail with third and fourth guests in a cabin, so passenger counts usually run above these figures. Hover or tap a bar for the month's ship calls.
What you get
Delivered as a spreadsheet, a monthly report for your ports, or a feed through the Cruise Itinerary API.
Read before you buy
The first and last day of every cruise are exact. For the stops in between we use the cruise line's own published itinerary wherever we have it, and those days are exact too. Where we do not, we place each call by the sailing distance between ports and flag it as estimated. In Alaska that is 49 of 2,177 calls in the 2027 season, 2%. Monthly and seasonal totals hold up well; an estimated mid-cruise day can be off by one. Until we have checked a port against its own published call schedule, we quote it by week and month, not by day.
Coverage is strongest for lines sold in North America. Some UK and European lines are missing: TUI Cruises and Marella, AIDA, Saga and Fred. Olsen among them. Send us your ports and we will tell you what we hold for each before you commit to anything.
Who it is for
Decide where to recruit operators and stock tours next season, from the ships already scheduled, across every port you list.
Run several ports? Move guides, vehicles and boats to where the berths are, month by month.
You know your own arrivals better than anyone. We show you the ports around you: which lines are moving capacity, and to where.
