Seas Remain Dangerous; Avoid the Water this Holiday

Seas Remain Dangerous; Avoid the Water this Holiday

The National Weather Service (NWS), Guam Weather Forecast Office advise trade-wind waves and swell will continue to produce hazardous sea conditions.


Many residents are off today and tomorrow due to the Christmas holiday and may have plans to be near the beach. To avoid serious injury, the Offices of Guam Homeland Security and Civil Defense (GHS/OCD) caution residents and visitors to remain out of the water or at the very least, to avoid east and north facing reefs and beaches until hazardous conditions subside. Rip currents will be life threatening. The following NWS advisories are in effect:


beach hazards statement remains in effect for Guam, Rota, Tinian, and Saipan through Tuesday afternoon. Persistent trade-wind swell has pushed large numbers of Portuguese man-of-war jelly fish toward the eastern and northern shores of the Marianas. The jellyfish have been seen on both the beaches and in the water.


Residents and visitors are advised to stay away from the waters and avoid touching jelly fish washed up on beaches as this can cause extreme pain.


high risk of rip currents remains in effect for Guam, Rota, Tinian, and Saipan along east facing reefs through at least Thursday morning. If caught in a rip current, yell for help. Remain calm and stay afloat while waiting for help. If swimming out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current. Rip currents will be life threatening.


small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 a.m. Thursday. East winds of 15 to 20 knots and combined seas of 8 to 10 feet will create hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
