Is now a good time to review your household's wildfire emergency and evacuation plan?

Hawaii experienced its third-wettest dry season in the last 30 years between May and September 2026. This period of above-average precipitation stands in contrast to the upcoming wet season, which is projected to see below-average rainfall.

Why it matters

The recent period of heavy rain has resulted in an accumulation of dry fuels, creating heightened wildfire risks for the state. Forecasters expect drought conditions to develop across many areas during the second half of the coming winter.

The 2026 dry season ranked as the third-wettest in a 30-year period, with only 3% of the state affected by drought at the start of May. While statewide drought was avoided, abnormal dryness persists in the Kona and South Kohala Districts.

The details

Above-average precipitation throughout the season was driven by active El Niño conditions. Increased wildfire potential now exists due to the combination of dry fuel accumulation from 2026 rain events and expected strong wind episodes.

May 2026 marked the start of the dry season.
The 2026 dry season spanned from May through September.
The wet season begins in October 2026 and concludes in April 2027.

Seasonal Patterns

The recent rainfall trends follow the trajectory established by the ongoing National Weather Service's El Niño climate advisory. This pattern reflects a departure from typical dry season dynamics, with projections indicating a return to below-average precipitation.

Residents should remain vigilant regarding wildfire safety due to the increased presence of dry fuel in the area. Local authorities advise monitoring weather alerts for strong wind episodes that could exacerbate existing fire risks.

The takeaway

While the heavy rainfall provided a wet dry season, the transition to a drier winter cycle with increased wildfire risk is a critical change for state residents. Implementing fire-prevention practices is recommended as the region enters the peak danger window.
