are these beaches up towards New England Worth Visiting ?

I want to plan a road trip to the following below

The Hamptons / Long Island / Fire Island New York

Martha’s Vineyard Massachusetts

Nantucket Island Massachusetts

Cape Cod Massachusetts

Jersey Shore New Jersey

Do they Offer Clear Enough Water to Snorkel or Scuba Dive ? How do they compare to Florida and Galveston when it comes to Water Clarity / Visibility ?

Thanks In Advance
