High Surf Warning In Effect Tuesday; Advisory Runs Thru Sunday


Guam – A High Surf Warning will be in effect from 6 am Tuesday to 6 am Wednesday morning, after which a High Surf Advisory will take effect and be in effect until Sunday  January 23erd at 6 pm.

The National Weather Service says that the warning, followed by the advisory are the result of  a strong cold front south of Japan which is producing a large area of gale force winds northwest of the Marianas. These winds are generating large swells which will create hazardous surf on north and west facing reefs throughout the Marianas, for the remainder of the week.


A high surf warning means that dangerous, battering waves will pound the reefs, producing deadly rip currents and potentially major coastal erosion and likely coastal inundation.

Expect hazardous surf to rise rapidly on north and west facing reefs starting early Tuesday morning. Surf will peak at 12 to 16 feet Tuesday afternoon. Surf will then diminish somewhat but remain hazardous for the rest of the week.

Precautionary/Preparedness Actions

Coastal erosion or property damage is possible in low-lying areas or where wave action is close to shore. This is most likely at high tide which occurs at around 7:30 am and 5:30 pm on Tuesday.

The high tide at 5:30 pm is 2.5 feet,  it will be one of the highest of the year.

Stay clear of life threatening surf along north and west facing reefs. Do not go out to see the surf!  Avoid venturing near exposed reefs and beaches especially those along north and west facing reefs as rip currents are life threatening.
