Panama Canal reduces draft for Neopanamax ships due to El Niño

The Panama Canal, a vital artery for global trade, is implementing a precautionary draft reduction for Neopanamax vessels, lowering the maximum allowable depth to 49.5 feet (15.09 meters). This adjustment, effective immediately, is a response to the anticipated strong El Niño phenomenon, which is expected to persist through 2027 and impact water availability.

While the canal administration assures that the daily number of ship transits will remain unchanged, the reduced draft means that Neopanamax ships, which represent a significant portion of the canal's traffic, will have to sail with less cargo. This could lead to logistical adjustments for shipping clients and potentially affect the canal's revenue, which is calculated based on tonnage.

The decision is directly linked to the current and projected water levels of Gatun Lake and Alhajuela Lake. These artificial lakes are the primary source of freshwater for the canal's operation and supply water to over half of Panama's population. The canal administration noted that this is a "habitual" measure during the dry season, typically from December to April. However, it was delayed this year due to an "unusually wet" summer in 2026.

This measure complements earlier water-saving initiatives implemented since December 2025 as part of preparations for the dry season and the potential El Niño event. In 2023, a prolonged dry season, exacerbated by El Niño, forced the canal to gradually reduce its draft to 44 feet for Neopanamax vessels and limit daily transits to 22, a situation that lasted for a year.
