NOAA's Storm Events Database holds 303 records for Guam, Guam from 1950 through June 30, 2026, on 268 days; the most frequent are rip current and surf records (90 records). 303 of them are forecast-zone records, which the National Weather Service files once per zone: a county covered by several zones receives each one, so a single storm can add several records on the same day. The deadliest single record is the June 29, 2004 high surf, filed for the forecast zone Guam, which covers the county: 5 deaths. FEMA has issued 22 declarations naming the county since 1976, 20 of them for natural hazards; the latest for a natural hazard was “Typhoon Bavi” on July 3, 2026.
The record, 1950 to 2026

Floods in the 2020-26: 17 records against 5 in the decade before, 17 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Guam days with a record above.
