Panama Canal to Slash Daily Vessel Traffic Amid Deepening El Niño Drought

The Panama Canal Authority announced on Thursday that it will reduce daily shipping volumes starting next month, citing a severe drought exacerbated by the El Niño climate phenomenon. This critical waterway, which links the Atlantic and Pacific oceans, faces unprecedented water scarcity.

Effective September 3, the daily limit for vessels transiting the canal will be lowered. The cap will drop from the current 36 ships to 34, and further decrease to 32 vessels per day by September 15. These adjustments are necessary due to critically low water levels in the canal’s watershed.

Central America is currently experiencing an intense drought, driven by El Niño—a climate pattern characterized by warming temperatures in the central and eastern equatorial Pacific, which disrupts global wind patterns, atmospheric pressure, and precipitation. As a vital artery of global commerce, the Panama Canal manages approximately five percent of worldwide maritime trade and roughly 40 percent of United States container traffic.

The canal’s water supply relies entirely on rainwater collected in two artificial lakes. The operator noted that lower than forecast rainfall in the canal’s watershed necessitates these actions to ensure the long-term sustainability of the waterway. In addition to limiting traffic, authorities have already implemented conservation measures, such as restricting the maximum draft—the vessel’s depth in the water—of the largest ships.

El Niño typically occurs every two to seven years, with the current event projected to be one of the most powerful on record. The widespread impact of this weather pattern was highlighted this week when the government of Honduras declared a drought alert covering 80 percent of its territory.
