Current U.S. Drought Monitor Conditions for Hawaii
The U.S. Drought Monitor (USDM) is updated each Thursday to show the location and intensity of drought across the country. This map shows drought conditions across Hawaii using a five-category system, from Abnormally Dry (D0) conditions to Exceptional Drought (D4). The USDM is a joint effort of the National Drought Mitigation Center, USDA, and NOAA. Learn more.
The following state-specific drought impacts were compiled by the National Drought Mitigation Center. While these impacts are not exhaustive, they can help provide a clearer picture of drought in Hawaii.
D0 - Abnormally Dry
- Corn quality declines; less water is available for irrigation
- Hiking trails are noticeably dry with soil erosion
64.4
of HI
(D0–D4)
D1 - Moderate Drought
- Pasture and crop growth is stunted; farmers are not allowed to use reservoir water for irrigation
- Concerns about fire danger increase
- Water levels decline; voluntary water restrictions are issued; reservoir levels are depleted in high elevations
34.7
of HI
(D1–D4)
D2 - Severe Drought
- Pasture conditions are very dry/poor; cattle health is poor; protea, coffee bean, sugar cane crops struggle
- Fire danger is high
- Reservoir levels are low; springs are dried up; mandatory water restrictions are implemented
14.4
of HI
(D2–D4)
D3 - Extreme Drought
- Producers cull cattle, buy supplements, and haul water for livestock
- Fires spread rapidly; outdoor burn bans are implemented
- Trees are dry and dropping leaves; feral donkeys move into populated areas
4.1
of HI
(D3–D4)
D4 - Exceptional Drought
- Cattle die; cattle conception rates are reduced
- Specialty crops, orchards are dying
- Hunting areas and hiking trails may be closed due to increased fire danger

Drought in Hawaii from 2000–Present
The U.S. Drought Monitor started in 2000. Since 2000, the longest duration of drought (D1–D4) in Hawaii lasted 388 weeks beginning on April 22, 2008, and ending on September 22, 2015. The most intense period of drought occurred the week of March 9, 2010, where D4 affected 6.59% of Hawaii land.
The U.S. Drought Monitor (USDM) is a national map released every Thursday, showing parts of the U.S. that are in drought. The USDM relies on drought experts to synthesize the best available data and work with local observers to interpret the information. The USDM also incorporates ground truthing and information about how drought is affecting people, via a network of more than 450 observers across the country, including state climatologists, National Weather Service staff, Extension agents, and hydrologists.
