Outlook

The Climate Prediction Center's drought outlooks at the center of Honolulu County: whether drought is expected to develop, persist, improve or end.

Monthly outlook, Sep 2026
No drought expected
Seasonal outlook, through December 31 (issued Sep 17)
No drought expected

The monthly outlook is issued on the last day of each month, the seasonal one on the third Thursday. CPC's discussion.

What drought has meant in Hawaii

The National Drought Mitigation Center's examples of impacts observed in Hawaii at each level of drought.

D0 Abnormally dry

  • Corn quality declines; less water is available for irrigation
  • Hiking trails are noticeably dry with soil erosion

D1 Moderate drought

  • Concerns about fire danger increase
  • More bugs observed than normal
  • Pasture and crop growth is stunted; farmers are not allowed to use reservoir water for irrigation
  • Water levels decline; voluntary water restrictions are issued; reservoir levels are depleted in high elevations

D2 Severe drought

  • Fire danger is high
  • Pasture conditions are very dry/poor; cattle health is poor; protea, coffee bean, sugar cane crops struggle
  • Reservoir levels are low; springs are dried up; mandatory water restrictions are implemented

D3 Extreme drought

  • Fires spread rapidly; outdoor burn bans are implemented
  • Producers cull cattle, buy supplements and haul water for livestock
  • Sugar cane producer lays off many employees
  • Trees are dry and dropping leaves; feral donkeys move into populated areas
  • Water production is reduced

D4 Exceptional drought

  • Cattle die; cattle conception rates are reduced
  • Hunting areas and hiking trails may be closed due to increased fire danger
  • Specialty crops, orchards are dying
  • Surface water is severely impacted
  • Tree beetle populations decline

Drawn from the Drought Impact Reporter and local observers.

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. Honolulu County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.

This week in the Pacific

The Drought Monitor authors' narrative for the map of Sep 22, 2026, released Sep 24, 2026.

Moderate precipitation over parts of Alaska resulted in reduction of abnormally dry regions in the state.

Hawaii is slowly recovering from tropical systems that passed nearby, with another system potentially coming close to the islands over the coming week.

Conditions across the Marshal islands brought intermittent showers and heavy rainfall for the northern islands keeping conditions status quo. This week, Utirik and Wotje recorded 1.75 and 2.58 inches respectively, though Ulirik is still in a precipitation deficit and has only recorded a little over half (4.27 inches) the necessary 8 inches per month. Elsewhere, after heavy rains last week, Ailinglapalap and Jaluit did not record any rainfall (1 day missing) while Kwajalein, Mili and Majuro received 0.54, 0.52 and 0.86 inches respectively. While Utirik did receive 1.74 inches this week, it follows several weeks of below adequate precipitation demand leading to the introduction of short-term abnormal dryness (D0-S).

The Federation States of Micronesia experienced varied rainfall with islands receiving well over 2 inches or under 0.15 inches. This week heavier rains fell across Chuuk Lagoon (2.30 inches, 1 day missing), Nukuoro (4.37 inches, 1 day missing) and Pohnpei (13.81, 1 day missing). Kosrae (0.25 inches, 5 days missing), Lukunor (0.14 inches, 2 days missing) and Kapingamarangi (0.02 inches, 1 day missing). Kapingamarangi has been below the necessary 2 inches a week for six weeks and has a monthly rainfall total of 3.08 inches leading to the degradation into short-term moderate drought (D1-S). Further west, there has been a short-term shift in weather towards the end of the week with monsoon showers bringing some short-term relief for Woleai (3.91 inches, 3 days missing), Ulithi (2.91 inches, 3 days missing) and Yap (4.73 inches, 1 day missing) before the dry pattern expected to return soon. Fananu and Pingelap had no data.

American Samoa saw generally decent rainfall. This week, Pago Pago received 5.6 inches (1 day missing), Siufaga Ridge 1.51 inches and Toa Ridge 1.74 inches (1 day missing). This week’s rainfall combined with last week’s heavy rainfall led to condition improving to short-term abnormal dryness (D0-S).

Palau experienced another week of inadequate precipitation and remain in short-term moderate drought (D1-S). This week with both Koror recording 1.87 inches while data was missing for WSO Palau/Airai. Conditions this week remain status quo with short-term moderate drought (D1-S).

This week, the Mariana Islands received heavy rainfall. Synoptic conditions favored active convection and locally heavy showers. Guam received an average of 4.09 inches this week with Antonio B Won Pat International Airport recording 5.64 inches, Agat 4.47 inches recording inches and Dededo recording 2.18 inches (2 days missing). Saipan averaged over 3.8 inches this week with Saipan International Airport recording 3.92 inches and Capital Hill recording 4.33 inches this week. Rota received 3.14 inches this week with the September monthly total already surpassing the necessary 4 inches (7.67 inches). Tinian had no data.

Looking ahead

The next five days are forecast to be wet along the northeastern coast from a nor’easter. The northwest is also predicted to receive needed precipitation. Remnants of a tropical system will provide significant moisture into the Four Corners states and the western Great Plains with heavy rainfall in the forecast. Parts of the northern Great Plains are also forecast to receive welcome precipitation. Areas with little rain in the forecast over the next five days are much of Texas and Louisiana, around the Great Lakes, and California and Nevada. The south and southwest should continue to have above normal temperatures, with cooler temperatures in the northeast and the northwest.

The 6- to 10-day outlook (September 29 to October 3) favors above normal temperatures over the southern half of the continental U.S. as well as the northeast. Hawaii is also likely to have above normal temperatures. The Great Basin area could have below normal rainfall, while above normal is possible over much of the central U.S. Both Hawaii and eastern Alaska are also favored to have above normal precipitation during this period.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
