George E. Price Jr., the seashore's superintendent, said the prohibition takes effect June 19. Smoking will still be allowed outside guarded areas, although smokers are not allowed to litter the beach with cigarette butts.
Non-smokers have complained about being subjected to second-hand smoke, Price said. A number of town beaches on the Cape already ban smoking and some other federal beaches, like the Fire Island National Seashore in New York, have similar prohibitions.
The Cape Cod seashore includes six swimming beaches with lifeguards: Coast Guard Beach and Nauset Light Beach, Eastham; Marconi Beach, Wellfleet; Head of the Meadow Beach, Truro; and Race Point Beach and Herring Cove Beach, Provincetown. Lifeguards are on duty from late June to late August.
