Severity Classification
The Drought Monitor assigns D4 to areas with extreme moisture deficits, indicating that crops cannot grow without irrigation and that natural vegetation is severely stressed.
Insight Notes
Puerto Rico has experienced a prolonged shortage of rainfall, leading to significant ecological, economic, and social consequences. This brief outlines the current drought status, its origins, the tangible effects on communities, and the measures in place to mitigate its impact.
Is There a Drought in Puerto Rico
THE ESSENTIAL BRIEF
The island’s recent climate pattern has produced less than half the average precipitation for the past four years, resulting in the National Weather Service’s Drought Monitor rating many regions as "D4," the most severe category. This sustained deficit has lowered water levels in reservoirs and aquifers, placing pressure on both municipal supplies and agricultural irrigation.
Historically, Puerto Rico’s water resources are heavily dependent on seasonal rains. The lack of sufficient rainfall has intensified the vulnerability of the island’s infrastructure, which already faces aging pipelines and frequent power interruptions. The combined stressors have amplified shortages, especially in rural communities reliant on well water.
KEY REFERENCE POINTS
Three essential facts that help understand the drought’s scope and its implications:
The Drought Monitor assigns D4 to areas with extreme moisture deficits, indicating that crops cannot grow without irrigation and that natural vegetation is severely stressed.
Reservoirs such as the San Juan and Río Culebrinas have dropped to below 30% capacity, prompting water rationing measures and emergency relief programs.
Agriculture, the island’s primary export of coffee and tropical fruits, has seen a 20% decline in yields, translating into lost revenue for farmers and downstream processing businesses.

Practical answers about Is There a Drought in Puerto Rico.
The drought condition began in late 2019 and has persisted, with the most severe levels recorded from 2020 through 2023.
A combination of reduced Atlantic rainfall, higher temperatures due to climate change, and the island’s complex topography that limits cloud formation over inland areas.
While increased rainfall could alleviate the situation, the current climate trend shows a reduction in tropical cyclone activity that brings precipitation to the region.
