What specific changes is the Panama Canal Authority implementing to address the drought, and when do they take effect?

The Panama Canal Authority will reduce daily ship transits from 36 to 34 starting September 3, and further lower the limit to 32 ships per day beginning September 15, due to reduced rainfall in the canal’s watershed. These measures are part of broader water conservation efforts, including lowering the maximum draft for the largest vessels, to ensure the long-term sustainability of the waterway amid a severe El Niño–driven drought.

Why is the Panama Canal particularly vulnerable to drought, and how does El Niño contribute to the current crisis?

The Panama Canal relies entirely on rainwater collected in two artificial lakes to operate its lock system, making it highly dependent on consistent rainfall in its watershed. The current drought is driven by El Niño—a climate pattern that warms surface waters in the central and eastern equatorial Pacific—disrupting global atmospheric circulation and reducing rainfall across Central America; this year’s El Niño is among the strongest on record, contributing to critically low water levels and prompting emergency operational adjustments.
