Panama Canal Delays Draft Reduction for Big Ships a Second Time as Super El Niño Looms

South America Ocean Freight News Report

What Happened?

The Panama Canal Authority (ACP) has further delayed a planned reduction in the maximum draft for the largest vessels transiting the Neopanamax Locks for the second time in a matter of weeks. The locks had been scheduled to cut the maximum draft to 14.48 meters at the start of the September, which was then pushed to October 1 and on to September 4th next, the ACP confirmed the Neopanamx Locks will instead continue at the current 14.63-meter maximum draft, with no reduction imposed as planned. The authority stated that the decision reflects its latest review of Gatun Lake Water levels and weather projections.

To manage this situation, the ACP has instead cut the number of daily transit slots: Panamax Locks slots were reduced to nine as of September 3, and older Panamax Locks transits were lowered to 25, with a further cut to 23 scheduled for September 15 the same balancing approach the authority used during the 2023 drought.

Why It Happened

The backdrop is a developing Super El Niño. The World Meteorological Organization warned on September 3 that there is now a near-100% likelihood El Niño will persist through February 2027, with UN Secretary-General António Guterres saying, "El Niño is being supersized before our eyes." However, the canal's data showcases a more stable near-term outlook that the Gatun Lake water levels have held fairly steady around 84 feet after dipping slightly below that level in late August, with the current forecast actually showing a slight rise of up to 0.4 feet into October typical for Panama's fall rainy season before decline is projected to resume. That gap between the alarming global El Niño forecast and the comparatively steady local lake data appear to be exactly why the ACP felt able to delay the draft cut rather than impose it pre-emptively.

What It Means

Maintaining the deeper 48-foot draft matters most for large containerships and gas carriers, which lose cargo capacity when draft restrictions force lighter loading. The stakes are real here as the gas carriers have already been diverting around South America to avoid canal constraints, and two gas carriers recently paid record-high auction prices to jump the transit queue. During the 2023-2024 drought, container vessels were forced to reduce loads by transshipping boxes across the isthmus via railroad a costly, capacity-denting workaround the ACP is clearly trying to avoid repeating. On the positive side, waiting times have actually eased: the average wait for a northbound non-booked transit is down to 8.8 days, with only four non-booked vessels waiting as of September 3 (three of them Neopanamax) against 85 vessels with reservations reinforcing the ACP's continued strong recommendation that ships use the booking/reservation system rather than risk a non-booked transit.

Short-Term Outlook

The ACP has explicitly framed this as a dynamic, closely monitored situation, and has committed to further updates on draft requirements as conditions evolve. With El Niño expected to strengthen toward peak intensity by year-end and persist into 2027, the real test will be whether Gatun Lake's currently stable levels hold through the usual fall rainy-season rise  if that seasonal replenishment underperforms, the currently delayed draft cut could return, potentially alongside further transit slot reductions.
