Fire Weather Planning Forecast for Hawaii
National Weather Service Honolulu HI
403 AM HST Sun Aug 17 2025

.DISCUSSION...
Conditions should remain below critical fire weather thresholds
into early next week. A low-level trough associated with the
remnants of former Tropical Cyclone Ivo will move across the
state later today through Monday, bringing an increase in
humidity and shower activity. By midweek, another plume of
moisture is expected in the vicinity of the islands, which may
increase shower activity again on Wednesday. Otherwise, expect
dry and stable conditions for the latter half of the week as high
pressure rebuilds across the islands. Temperature inversion
heights near Maui and the Big Island today will range from the
4,500 to 5,500 feet elevation level.
