High Surf Advisory issued October 5 at 2:19AM EDT until October 7 at 5:00PM EDT by NWS Melbourne FL
Effective: Sun October 5, 2025, 2:19 AM
Expires: Tue October 7, 2025, 5:00 PM
* WHAT...For the Coastal Flood Advisory, minor coastal flooding. For the High Surf Advisory, breaking waves of 5 to 7 feet in the surf zone. For the High Rip Current Risk, dangerous rip currents. * WHERE...Coastal Volusia, Coastal Brevard, Coastal Indian River, Coastal Saint Lucie and Coastal Martin counties. * WHEN...For the Coastal Flood Advisory and High Surf Advisory, until 5 PM EDT Tuesday. For the High Rip Current Risk, through Tuesday afternoon. * IMPACTS...Some flooding of low-lying lots, parks and roadways may occur near the shoreline. Only isolated road closures are expected. Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water.
Onshore winds and above normal tides will combine to generate flooding of low areas along the shore. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. High surf will affect the beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions. Swimmers should remain out of the water due to large breaking waves and dangerous surf conditions. 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 jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. Entering the surf is strongly discouraged. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
