High Surf Advisory issued February 4 at 5:09PM AST until February 5 at 6:00AM AST by NWS San Juan PR
Effective: Wed February 4, 2026, 5:09 PM
Expires: Thu February 5, 2026, 6:00 AM
* WHAT...For the High Surf Advisory, large breaking waves of 10 to 12 feet. For the High Rip Current Risk, life-threatening rip currents. * WHERE....Beaches of northwestern to northeastern Puerto Rico. The most vulnerable areas for high surf and beach erosion include Pinones along road 187, Parcelas Suarez, Villas del Mar, and Villa Cristiana in Loiza; Fortuna in Luquillo; Pueblo and Tamarindo in Aguadilla; Barrio Obrero, Pueblo and Jarealito in Arecibo; La Boca in Barceloneta; Machuca in Manati; Puerto Nuevo in Vega Baja; and Ocean Park in San Juan. * WHEN...For the High Surf Advisory, until 6 AM AST Thursday. For the High Rip Current Risk, through late Friday night. * IMPACTS...Rip currents that can sweep even the best swimmers away from shore into deeper water where it becomes difficult to return to safety. 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 some beach erosion with only minor damage possible to dune structure.
A High Surf Advisory means that high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions. 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.
