Fire Weather Planning Forecast for Guam
National Weather Service Tiyan GU
401 AM ChST Thu Nov 13 2025

.Discussion...
0.34 inches of rain fell yesterday at the Guam International
Airport, which allowed the KBDI to diminish slightly to 102, which is
still in the low category. Only 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 next Wednesday. Winds could pick up
next Thursday though, so keep an eye on that for the second half of
next week.
