Rip Current Statement issued December 22 at 8:37PM AST until December 26 at 6:00AM AST by NWS San Juan PR

Effective: Mon December 22, 2025, 8:37 PM
Expires: Tue December 23, 2025, 4:45 AM

* WHAT...High Rip Current Risk, life-threatening rip current. * WHERE...Beaches from northwestern to northeastern Puerto Rico. * WHEN...From Tuesday evening through late Thursday night. * IMPACTS...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.

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.
