Seasonality of the global cruise industry

Seasonality is a unique characteristic of the cruise industry. Cruise lines move their ship deployment areas seasonally to meet tourism needs. Taking advantage of the climatic differences between the Northern and Southern Hemispheres could allow greater growth in the global cruise industry. This study aims to provide basic findings for governments and ports to consider ways to encourage growth by capitalizing on the seasonality of the global cruise industry. Automatic identification system data for all ocean-going cruise ships worldwide in 2019 were compiled and categorized into three travel groups (short, middle, and long) based on the latitudinal distance traveled. Differences between these three groups were analyzed in terms of deployment area/port, vessel size, and itinerary design. As a result, we found that the long travel group had the following characteristics. Cruise ships were deployed to Alaska and Northern Europe in summer and dispersed to the equator and Southern Hemisphere in winter. The vessel size was standard and neither too large nor too small. Specifically, long travel of cruise ships was limited by the maximum gross tonnage, length, and breadth of the ship, but there was no draught restriction. Although the number of nodes and edges, and the average degree comprising the itineraries were high, hub ports appeared only in the summer. Furthermore, despite the long distances traveled by season, the number of communities tended to be small, reflecting the design of their itineraries. In conclusion, the development of several ports in the Southern Hemisphere that can accommodate mega-sized cruise ships with standard draught, while considering overtourism, would allow cruise ships to take advantage of the seasonality and, thereby, grow the cruise industry
