Panama Canal to reduce Neopanamax draft starting July 3

The Panama Canal Authority (ACP, for its Spanish acronym) is reducing the maximum authorized draft for vessels transiting the Neopanamax locks to 49.5 feet, starting July 3. The decision was communicated to shipping lines via an official notice and is part of the ongoing water management strategy to ensure operational sustainability amid potential adverse weather conditions.

According to the authority, this seasonal adjustment will not alter the number of daily transits and is expected to affect less than 1.7 percent of Neopanamax vessels using the route.

Panama Canal braces for El Niño

The ACP initiative complements water-saving actions implemented by the company since December 2025, designed to prepare for the 2026 dry season and the potential development of the El Niño phenomenon in the second half of the year. Projections indicate that the weather event could extend into 2027, potentially impacting water availability in the basin.

While preventive restrictions are standard during the dry season, the authority noted that this specific measure is coming back for the first time in nearly two years. Favorable rainfall conditions throughout 2025, combined with an unusually wet start to the 2026 dry season, had previously enabled the canal to maintain optimal reservoir storage levels.

The latest decision incorporates insights from the 2023/24 water crisis. It is based on a comprehensive analysis of historical statistics, technical measurements, and hydrological projections, allowing the ACP to anticipate various scenarios and adopt timely measures to ensure service reliability.
