Fire Weather Planning Forecast for Guam
National Weather Service Tiyan GU
428 AM ChST Sat Nov 15 2025

.Discussion...
0.01 inches of rain fell yesterday at Guam International Airport,
which allowed the KBDI to rise to 149, which is still in the low
category. Mainly isolated showers are expected through 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 the weekend. Winds may 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 prevent widespread
fire activity.
