Fire Weather Planning Forecast for Guam

305 AM ChST Tue Nov 25 2025

.Discussion...
0.01 inches of rain has fallen yesterday at Guam International Airport,
allowing the KBDI to increase to 243, which remains in the low
category. Trade winds will continue to dominate this week as a drier
regime settles in, so the KBDI is expected to continue to slowly
creep up through at least Tuesday night. While the overall fire danger
remains low, caution is still recommended with any outdoor burning
during periods when strong trade winds are present.
