Rip Current Statement issued July 2 at 3:05AM EDT until July 2 at 9:00PM EDT by NWS Upton NY

Effective: Thu July 2, 2026, 3:05 AM
Expires: Thu July 2, 2026, 9:00 PM

* WHAT...Dangerous rip currents. * WHERE...Kings (Brooklyn), Southwest Suffolk, Southeast Suffolk, Southern Queens and Southern Nassau Counties. * WHEN...Through this evening. * IMPACTS...Life-threatening rip currents are likely for all people entering the surf zone. Anyone visiting the beaches should stay out of the surf. Rip currents can sweep even the best swimmers away from shore into deeper water.

If you enter the surf zone, always have a flotation device with you and swim near a lifeguard. If caught in a rip current, relax and float, and do not swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and yell 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.
