The Panama Canal is planning another reduction in maritime traffic as a severe drought caused by the El Nino weather pattern puts pressure on the waterway’s ability to maintain normal operations. The canal has already reduced the number of ships allowed to transit each day in an effort to conserve water, and authorities now plan to lower the average number of daily crossings further from October. Panama has declared a nationwide emergency over El Nino, which is developing over the Pacific Ocean and affecting weather patterns around the world while contributing to rising global temperatures. The situation is creating significant challenges for a waterway that is vital to international trade and depends on large quantities of water to operate its locks.

The Panama Canal is particularly vulnerable to prolonged drought because its system of locks relies on freshwater to raise and lower ships as they move between the Atlantic and Pacific oceans. Around five percent of global trade passes through the canal, making any disruption to its capacity potentially significant for international shipping. The drought in Central America has reduced the availability of water required for canal operations, forcing authorities to balance the needs of shipping with the need to preserve water supplies. With El Nino expected to be exceptionally strong this year, canal officials are preparing for continued pressure on water resources.

As part of those efforts, canal authorities reduced daily transits from 36 to 32 on September 4 to conserve water. The restrictions are expected to become more severe from October, when the canal plans to allow an average of 29.5 transits per day, according to a draft budget submitted to Panama’s parliament. The planned reduction represents another step in the canal’s efforts to manage its available water resources while keeping the waterway operational. The measures are intended to ensure that the canal can continue handling maritime traffic despite the difficult weather conditions and the resulting strain on its water supply.

Panamanian officials have emphasized that the reductions are designed to protect the canal’s long-term operations while maintaining its essential role in global shipping. Minister for Canal Affairs Jose Ramon Ycaza said the approved budget ensures that the canal continues to operate safely, continuously, efficiently and profitably. The comments underline the importance of maintaining the waterway’s operations even as authorities introduce restrictions on the number of vessels that can pass through each day. The challenge for canal authorities is to manage the available water carefully without compromising the safety and reliability of the interoceanic route.

The expected strength of this year’s El Nino has added to concerns over the canal’s water supply. The phenomenon is expected to be the strongest since record-keeping began four decades ago, according to the information provided. A previous episode in 2023 demonstrated how severely the weather pattern can affect canal operations. During that period, authorities were forced to reduce daily transits from 38 to 22 as water shortages made it necessary to impose tighter restrictions. The current reductions therefore reflect concerns that the canal could again face significant operational pressure if drought conditions persist or intensify.

The latest restrictions are also being introduced at a time when traffic through the canal has been affected by disruptions elsewhere in global shipping. The US-Israeli war on Iran has pushed up traffic through the Panama Canal as shipping activity has been affected by the standstill in the Strait of Hormuz, a key route for roughly a fifth of the world’s oil and gas. This creates an additional challenge for the Panama Canal, as demand for its services can rise even while its ability to accommodate ships is being constrained by water shortages. With daily transits already reduced and another cut planned from October, canal authorities will have to manage limited water resources while continuing to support global maritime trade. The strength and duration of El Nino will remain important factors in determining how long the restrictions may need to remain in place.
