High Surf Advisory
Urgency:
Expected
Effective:
October 18, 2026 - 12:53am
Expires:
October 18, 2026 - 11:00am
Description:
* WHAT...For the High Surf Advisory, large breaking waves of 10 to
14 feet in the surf zone. For the High Rip Current Risk, dangerous
rip currents.
* WHERE...South and west facing reefs of Guam and Rota.
* WHEN...Until 4 AM ChST Monday.
* IMPACTS...Dangerous swimming and surfing conditions and
localized beach erosion. Rip currents can sweep even the best
swimmers away from shore into deeper water.
* ADDITIONAL DETAILS...As Super Typhoon Champi continues moving away
from the region, surf has fallen below life-threatening levels but
will remain hazardous at least through tonight. In addition, storm-
induced coastal inundation and significant coastal erosion are no
longer expected. Even so, minor wave run-up can still occur.
Instruction:
Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.
Rip currents will be life threatening. If caught in a rip
current, relax and float. Don't swim against the current. If
able, swim in a direction following the shoreline. If unable to
escape, face the shore and call or wave for help.
