Fire Weather Planning Forecast for Guam
National Weather Service Tiyan GU
447 AM ChST Fri Nov 14 2025

.Discussion...
0.04 inches of rain fell yesterday at Guam International Airport,
which allowed the KBDI to rise to 124, which is still in the low
category. Mainly isolated showers are expected through the middle of
next week as a drier trade-wind regime continues, which should allow
the KBDI to generally rise through then. Winds will remain gentle to
moderate through Saturday night. Winds could pick up after that,
becoming moderate to fresh next week, and maybe even higher Wednesday,
so keep an eye out for that. For now, antecedent moisture will help
to prevent widespread fire activity.
