Today looks like it'll be a beautiful beach day, but even spectacular weather can't spare you from the unpleasantness that is swimming in bacteria-filled water. So if you're planning on heading to a Long Island beach today, it may behoove you to heed the Nassau County Department of Health advisory issued for 19 of its beaches today due to potential bacteria.

The Health Department says storm water runoff may have contaminated a slew of local beaches. Officials are warning visitors to avoid swimming in the following waters:

  • Centre Island Sound in Bayville
  • Creek Club in Lattingtown
  • Lattingtown Beach in Lattingtown
  • Laurel Hollow Beach in Laurel Hollow
  • Morgan Sound in Glen Cove
  • North Hempstead Beach Park in Port Washington
  • Piping Rock Beach Club in Locust Valley
  • Pryibil Beach in Glen Cove
  • Ransom Beach in Bayville
  • Theodore Roosevelt Beach in Oyster Bay
  • Sea Cliff Village Beach in Sea Cliff
  • Soundside Beach in Bayville

  • Biltmore Beach Club in Massapequa
  • Hewlett Point Beach in East Rockaway
  • Island Park Beach in Island Park
  • Merrick Estates Civic Association in Merrick

No word on how bacteria might affect all our new shark friends, but they'll probably be just fine.
