Puerto Rico faces an unprecedented drought crisis, with extreme conditions now covering 44% of the island as of August 25, 2026 1. Three-quarters of the territory is experiencing at least moderate drought, compounding the humanitarian and economic challenges across the region 1.

The severity of the precipitation deficit has been striking across Puerto Rico. From mid-May through mid-July, most areas received less than 60% of their normal rainfall, while southern and southwestern regions saw precipitation plummet to just 20% of typical levels, creating a rainfall deficit of 3 to 6 inches (76-152 millimeters) 1. San Juan recorded one of its hottest temperatures on record in July 1. In response to the water crisis, multiple municipalities implemented water rationing beginning in early August 1, and the governor declared a state of emergency late in the month 1.

The drought's economic impact extends across agricultural sectors and beyond. Crops including fruit, cacao, bananas, and coffee have suffered significant damage, while forage supplies for livestock have dwindled dramatically 1. The crisis prompted the U.S. federal government to issue drought disaster declarations for more than 20 towns and cities by the end of August 1, opening pathways for emergency assistance to affected communities.
