Fire Weather Planning Forecast for Hawaii
National Weather Service Honolulu HI
306 AM HST Wed Aug 20 2025

.DISCUSSION...

Moderate to locally breezy trade winds are expected as high
pressure builds over the state. Inversion heights look to be in
the 5,500 to 6,500 foot range today. Despite lowest RH values
dipping as low as the mid 40s during the afternoon hours each day,
wind speeds look to be a limiting factor, so not expecting any
fire weather headlines today.
