How do destinations forecast cruise passenger volumes?
Last updated · schedules published by 28 September 2026
Destinations forecast cruise volume from the lines' own schedules: berth bookings made one to three years ahead, multiplied by each ship's lower berths and an occupancy factor above 100%. Consultants such as Bermello Ajamil and Tourism Economics model further out. Port Day's schedule count holds 91% of official Alaska calls.
Destinations forecast cruise passenger volumes by counting the ships the cruise lines have already scheduled, then converting ship capacity into passengers. The schedule is the forecast for the next two or three seasons; economic models take over after that. This guide sets out the method, the occupancy figures it depends on, and how closely a schedule count matches official port calendars.
How do cruise ports forecast passenger numbers?
Cruise ports forecast passenger numbers from the cruise lines' own schedules. Lines reserve berths one to three years ahead, so a port already knows most of next season's ships. The port multiplies each call by the ship's lower berths, applies an occupancy factor, and for home ports counts embarking and disembarking passengers separately.
- Collect the berth reservations or published itineraries for the season.
- Give each call the ship's lower berths, two per cabin.
- Apply an occupancy factor, usually above 100% because cabins carry third and fourth guests.
- For a home port, count passenger movements: each guest embarks once and disembarks once.
Juneau writes the lead time into its 2024 agreement with the largest lines: ship schedules are discussed two years in advance. The Port of Galveston projected 3.9 million embarkations and debarkations across 445 sailings for 2026, a figure its port director based on cruise line commitments, as The Galveston County Daily News reported in December 2025.
Why does cruise occupancy above 100% matter for forecasts?
Cruise occupancy is reported against two guests per cabin, so it regularly exceeds 100%. Royal Caribbean Group reported a 109.7% load factor for 2025 and Carnival Corporation 105% for its 2025 fiscal year. A forecast that counts lower berths alone therefore undercounts passengers by five to ten percent.
The factor moves with the season. Carnival Corporation reported 111.8% for its third quarter of 2026, the northern summer, against 106.5% for the first nine months of the year. Royal Caribbean Group reported 110.2% for its second quarter. A single annual factor understates summer and overstates the shoulders, so Port Day reports lower berths and leaves the occupancy assumption to the buyer, who often knows it better for their own port.
What do Tourism Economics and Bermello Ajamil add?
Tourism Economics, an Oxford Economics company, sells Cruise IP, which models 460 ocean-going ships across more than 3,000 ports and gives a five-year outlook for passenger demand. Bermello Ajamil & Partners writes commissioned cruise market studies and port master plans, such as PortMiami 2035 and Port Canaveral 2047.
Cruise IP adds what a schedule cannot: monthly data with quarterly forecasts beyond the published schedules, pricing by cabin type, and demand modelling by region. Its page shows CLIA and FCCA among its users. Bermello Ajamil monitors passenger trends, fleet orders and deployments for ports and tourism boards, and its master plans include Galveston, Port Everglades and the Skagway waterfront. Both answer the question a schedule cannot reach: what happens after the lines stop publishing, three or more years out.
How does Port Day forecast cruise capacity by port?
Port Day reads the published schedules of 42 cruise lines every week, covering 517 ships with sailings to 2030. It places every sailing on the calendar, counts each ship once per port per day, and multiplies by the ship's lower berths. The output is ship calls and lower berths by port and month.
- Port Day calls
- CLAA calls
First and last days of each cruise are exact. For the stops between, the feed lists ports in order but not the date of each, so Port Day places them by sailing distance, and replaces the estimate with the line's own published itinerary where it has fetched one. Port rows that are the same place are merged. The result is a schedule forecast, not a demand forecast: it holds what the lines have published, and it moves when they add, cancel or reroute a sailing.
How accurate are schedule-based cruise forecasts?
Against the official Cruise Line Agencies of Alaska schedule, Port Day holds 91% of calls, places 83% on the exact date and 94% within one day. At Port Canaveral it holds 94% of calls. Monthly totals are reliable in North America; single days and European ports are weaker.

Port Day against official port schedules, latest weekly check. Held = the ship is at that port within six days in our data. Same day and within a day are shares of the calls compared. Barcelona: Font: Port de Barcelona.
A first check against CLAA on 3 October 2026 found about 60% of mid-cruise Alaska calls on the exact date. The figure rises as official line itineraries replace distance estimates, and this page reports the latest weekly check. Monthly Juneau call counts run 10 to 14% above CLAA from May to September, mostly small expedition ships CLAA does not schedule; lower berths are closer. Low shares mean missing ships, not misplaced calls: in Europe whole lines are absent (TUI Cruises and Marella, AIDA, Saga, Fred. Olsen and Hapag-Lloyd), and in Australia many sailings of lines we do carry are not in our feed.
What are the limits of a schedule-based forecast?
A schedule-based forecast counts only what cruise lines have published, so it thins out beyond two or three seasons, misses lines that are not in the source, and cannot say how full each ship will sail. Ports that need passenger numbers still apply an occupancy factor, and ports that need a ten-year view still commission a study.
Single days are the other limit. A one-day slide of a mid-cruise call leaves a monthly total unchanged but moves a ship from a quiet Monday to a busy Tuesday, which is exactly the question a capped port asks. For a specific date, the authority is the port's own berth schedule, such as the CLAA calendars in Alaska. Port Day publishes months and seasons, where the comparison above shows the count holds.
Key takeaways
- Cruise forecasts start from berth reservations and published itineraries, which lines set one to three years ahead.
- Lower berths times an occupancy factor gives passengers; reported occupancy ran from 105% to 111.8% in 2025 and 2026.
- Port Day holds 91% of official Alaska calls and places 94% within one day of the official date.
- Schedule counts are reliable by month in North America and weaker for single days and European ports.
- Tourism Economics and Bermello Ajamil cover what schedules cannot: demand, pricing and the years beyond published sailings.
Frequently asked questions
How far ahead can a port forecast cruise passengers?
About two to three seasons from schedules alone. Cruise lines reserve berths and publish itineraries one to three years ahead; Juneau's agreement with the largest lines discusses schedules two years in advance. Beyond that, forecasts rely on economic models, such as the five-year outlook in Tourism Economics Cruise IP, or a commissioned study.
Why are cruise passengers higher than ship capacity?
Ship capacity is quoted in lower berths, two per cabin. Many cabins carry a third or fourth guest, so ships sail above 100% occupancy. Royal Caribbean Group reported a 109.7% load factor for 2025 and Carnival Corporation 111.8% occupancy for its third quarter of 2026, the northern summer.
How accurate is a cruise schedule forecast?
By month it is close. Against the official Alaska schedule, Port Day holds 91% of calls and places 94% within a day of the official date. Single mid-cruise days are less reliable, and European ports read low because several European lines are missing from the data.
Who makes cruise passenger forecasts for ports?
Ports usually start in house from the lines' berth bookings. For longer views they buy data from Tourism Economics, whose Cruise IP lists CLIA and FCCA among its users, or commission studies from consultancies such as Bermello Ajamil & Partners, which has written master plans for PortMiami and Port Canaveral.
