If you mean clean = no seaweed welcome to New England. Not as nice as outer cape / CC National seashore or parts of Maine but also not as cold as Maine and defo nicer than CT beaches!

But comparing beaches in different temperature zones is foolish anyway. There’s stunning beaches in Ireland for example that beat Florida by a mile but it’s not warm. I hate any kind of beach next to overdevelooed areas / condo towers for example so going to Florida is the last thing I’d want to do for a beach.
