Fire Weather Planning Forecast for Hawaii
National Weather Service Honolulu HI
353 AM HST Mon Aug 18 2025

.DISCUSSION...
Conditions should remain below critical fire weather thresholds
through the first half of this week. A weak low-level trough will
continue to move across the state today, bringing an increase in
humidity and shower activity and weakening the trade wind
inversion. 12Z sounding from Lihue shows the trade wind inversion
has lifted from 5000 feet Sunday afternoon to 9000 feet early this
morning. As the trough exits the area tonight, we should see the return
of stable and dry conditions by Tuesday afternoon. During the
second half of the week we should see stable and dry conditions
with a stronger trade wind inversion at around 5000-6000 ft.
Breezy trades are also expected during this time, which could
produce elevated fire weather concerns later in the week through
next weekend.
