The improvement of Gatun Lake level in the Panama Canal has reached near the historical average due to unexpected rainfall in October. While forecasts warned of the possibility of prolonged droughts due to the El Niño phenomenon, the heavy rains in October have changed the conditions and helped restore the operations of the canal.
Details of Rainfall and Lake Level Improvement
According to new data from Ursa Shipbrokers, which referenced data from the Panama Canal Authority, the level of Gatun Lake averaged 85.80 feet (26.15 meters) during the first 30 days of October, which is only 0.15 feet below the historical average for this month. This increase in water level is notably significant compared to 2023, when severe drought impacted the canal, with the average water level in October 2023 being 6.04 feet higher than the same month in previous years.

Rainfall Statistics and Their Impact on Canal Operations
Rainfall statistics indicate an improvement in the hydrological situation in the region. Data collected from weather stations of the Panama Canal Authority shows that from October 1 to October 29, 303.3 millimeters of rain fell in the watershed of this lake, which is 8.4 percent more than the 30-year average and 83.6 percent more than the same period in 2023. On October 29, the daily level of Gatun Lake reached 86.56 feet, showing a significant increase from its lowest level in August of 83.80 feet.
With the improvement in weather conditions, the Panama Canal Authority has been able to lift some restrictions. As of October 15, the number of ships allowed to transit daily has increased to 33 vessels, and the maximum depth for Neopanamax ships has risen to 49 feet. Additionally, last-minute reservations for Panamax ships have also become possible again.
However, the threat of drought has not been completely eliminated. Rainfall from May to now has been nearly 20 percent below average, and we have experienced a very dry summer during which watershed inputs were 44 percent lower than normal. With the forecast of the El Niño phenomenon continuing until 2027, the upcoming dry season will be a significant test of whether the favorable rains in October have been sufficient to prevent the re-imposition of restrictions.
