High Surf Advisory issued March 31 at 3:57AM AST until April 1 at 6:00PM AST by NWS San Juan PR

Effective: Tue March 31, 2026, 7:57 AM
Expires: Tue March 31, 2026, 10:00 PM

* WHAT...For the High Surf Advisory, large breaking waves of 8 to 12 feet. For the High Rip Current Risk, life-threatening rip currents. * WHERE... For the High Surf Advisory, the most vulnerable areas for high surf and beach erosion are the exposed north-facing beaches in Culebra and the northern US Virgin Islands. For the High Rip Current Risk, along the north-facing beaches today, expanding to most beaches tonight. * WHEN...For the High Rip Current Risk, remains from Tuesday morning through Friday evening. For the High Surf Advisory remains, through 6 PM AST Wednesday. * IMPACTS...For the High Surf Advisory, high waves that can wash over jetties and sweep people and pets onto jagged rocks. Rough surf may also knock you down. Large breaking waves will result in localized beach/dune structure erosion and dangerous swimming conditions. For the High Rip Current Risk, rip currents can sweep even the best swimmers away from shore into deeper water, where it becomes difficult to return to safety.

There is a high risk of rip currents. Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as groins, jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. If you become caught in a rip current, yell for help. Remain calm, do not exhaust yourself and stay afloat while waiting for help. If you have to swim 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 as you will tire quickly. A High Surf Advisory means that high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
