Has not been a good snow year, I would expect most if not all salting to be done by April 1st. My fiance's family has a lake house in that area so I spend a decent amount of time up there, I can't imagine not having a car up there.
There is some surfing in New England, summer months are usually not the best swell but it might be worth while to bring your board, with a car you'll be able to hit spots from Maine to Rhode Island within a couple hours drive.
