Read the NWS Warning & Advisory

A high surf warning remains in effect until 6 am Wednesday. 

A High Surf Advisory remains in effect from 6 am Wednesday to 6 pm Sunday.

A High Surf Warning means that dangerous, battering surf will pound the reefs, producing deadly rip currents, coastal erosion and coastal inundation are also likely.

Expect hazardous surf to rise rapidly on north and west facing reefs starting early this morning on Saipan and around mid-morning on Guam. Surf will peak at 12 to 16 feet this evening and tonight.

Surf will then diminish to 9 to 13 feet Wednesday but remain hazardous for the rest of the week.

Precautionary/Preparedness Actions

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

Stay clear of life threatening surf along north and west facing reefs. Do not go out into the surf!
