There will be ocean plunges Sunday at Gurney’s Inn in Montauk, at Main Beach in East Hampton Village, and at Beach Lane in Wainscott.
The Gurney’s one, which benefits the Retreat, is to go off at 10:30 a.m., the Main Beach one at 1 p.m., and the Wainscott one at 2:30.
The Main Beach plunge, put on by the East Hampton Volunteer Ocean Rescue Squad and sponsored by the Y.M.C.A. East Hampton RECenter, benefits the East Hampton food pantries.
Plungers, who have been asked to solicit donations, are to register at Main Beach from 11:30 a.m. to 12:30 p.m. Coffee, hot chocolate, soup, chili, and hot dogs will be served by East Hampton Y.M.C.A. Hurricane swim team parents.
The Wainscott plunge — the granddaddy of the plunges here — is to begin with a run to the beach with Colin Mather from his Seafood Shop on Montauk Highway at 2.
