To help residents beat the heat, both counties have opened cooling stations, and some state and county beaches and pools will be open later Tuesday.

Cooling stations are open from 9 a.m. to 9 p.m. for the next two days. Residents without air-conditioning can go to the stations to cool off if they are in need of some relief.

In Nassau, cooling stations are at the North Massapequa Community Center, 214 N. Albany Ave. in North Massapequa, and at the Sandel Senior Center, 50 S. Park Ave. in Rockville Centre.

Suffolk has opened a cooling station at the Islip Senior Citizen Center, 16 S. Second Ave., Brentwood. The center is close to public transportation, Suffolk County Executive Steve Levy said.

At state park beaches, such as Robert Moses, Jones Beach, Heckscher and Sunken Meadow, lifeguard hours have been extended an hour until 8 p.m. through the week and until 7 p.m. at the West Bathhouse pool, officials said.

Nassau's four major swimming pools will also be open longer than usual. The pools at Cantiague and Christopher Morley parks will be open until 7 p.m. Wantagh Park's will be open until 7:45 p.m. and North Woodmere's pool will be open until 8 p.m.

"Nassau County's outdoor pools provide residents with a terrific place to exercise, have fun and beat the heat, and with the temperatures climbing to particularly oppressive levels, we're going to provide an extra hour of relief," Nassau County Executive Edward Mangano said.

Nassau pools are only open to county residents, and there is a fee. Visit nassaucountyny.gov/parks or call 516-572-0200 for further information.
