The year 2025 was the fifth driest in Cuba since 1901, with a total accumulated rainfall of 1,114 millimeters — equivalent to 83 percent of the historical average. The highest regional precipitation occurred in the eastern part of the country, at 94 percent, a figure largely influenced by Hurricane Melissa. These findings were shared exclusively with the Cuban News Agency by the Institutional Communication Directorate of the National Institute of Hydraulic Resources (INRH), as part of a broader assessment of the country's hydrological conditions last year.

According to the institution, the central region recorded 82 percent of its historical precipitation average, while the western region reached only 74 percent. Reservoirs closed the year holding 5,868 cubic hectometers, representing 64 percent of total capacity and falling 228 cubic hectometers below the traditional annual average.

As a consequence, 14 of the country's 101 principal aquifers were found to be in an unfavorable condition, with one classified as critical, the INRH noted in its summary of hydrological management results for the year.
