PANAMA / RankWire.AI / – The Panama Canal is contemplating a further reduction in the number of ships crossing daily, as ongoing drought conditions threaten its water reserves. Ilya Espino de Marotta, the canal’s administrator, indicated that traffic may decline to approximately 29 vessels per day in February or March 2027. Any additional restrictions will depend on persistent dry weather and reservoir water levels. The waterway is already approaching a cap of 32 transits per day starting September 15.
The Panama Canal Authority initiated capacity cuts following below-average rainfall and watershed inflows during the wet season. Initially, daily transits decreased from the usual 35 to 34, then to the planned limit of 32. The canal relies on freshwater stored in Gatun Lake and Alhajuela Lake to operate its locks, with each transit requiring water to elevate or lower ships between the Atlantic and Pacific Oceans.
Data for fiscal 2026 shows an average of 35 daily transits through June 30, with a total of 10,726 crossings from October to June—representing a 5.2% rise compared to the same period in the previous year. These figures predate the worsening rainfall conditions that prompted new operational restrictions. Despite these challenges, the canal remains a vital route for container ships, tankers, bulk carriers, and other vessels involved in global trade.
Reservoir levels determine operational capacity
Water resource levels have historically dictated how many ships can traverse the canal during dry spells. During the severe drought of 2023, daily crossings dropped to 22 in December as Gatun Lake’s water levels fell to unusually low points. Conditions improved with rainfall returning and water conservation measures aiding reservoir recovery. Canal officials continue to monitor lake levels, watershed inflows, and precipitation to set daily operational limits.
Additionally, vessel draft regulations have been adjusted as part of current water management strategies. The previously planned reduction of Neopanamax vessel draft to 47.5 feet was postponed after an assessment of reservoir conditions, keeping the maximum draft at 48 feet. Draft limits influence how deeply ships sit in the water and can affect cargo capacity during transit.
Reduced transit slots lead to stricter booking procedures
The canal has revised its booking and auction processes as available transit slots decrease. Auction categories now separate vessels based on cargo types, such as container ships, gas carriers, tankers, and bulk carriers. Priority is given to full container ships with larger capacity for some Neopanamax allocations when other conditions are equal. Officials are urging vessels without reservations to utilize the booking system, as confirmed bookings guarantee scheduled transit dates.
While no official announcement has been made to cut traffic to 29 ships daily, Espino de Marotta mentioned that level as a potential restriction if dry conditions persist into early 2027. The canal is also progressing with the Río Indio reservoir project to boost long-term water storage. Authorities state that this project will support canal operations and help ensure water availability for a significant portion of Panama’s population.
