Beach Hazards Statement issued May 3 at 1:15AM EDT until May 4 at 3:00AM EDT by NWS Melbourne FL

Effective: Sun May 3, 2026, 1:15 AM
Expires: Mon May 4, 2026, 3:00 AM

* WHAT...A developing southward flowing longshore current and a Moderate risk of rip currents is expected. * WHERE...The beaches of Volusia, Brevard, Indian River, Saint Lucie, and Martin counties. * WHEN...Through late tonight. * IMPACTS...North winds 15 to 20 mph and gusty behind a cold front will produce a north to south current parallel to the coast. These currents can push swimmers into deeper water and possibly into rip currents.

Swim near a lifeguard. 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.

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.
