As many have implied, we're going to need a bit more information from you to make any positive contribution to your search. For instance, tell us what is important to you: cost of living (aka, what you can afford (ie: Boston versus Albany cost of living?); close to water or close to mountains; in the water or just on the water access; cold versus hot (you seemed to imply cold); urban versus rural; cultural activities or unibomber shack isolation?
Just some perspective on my background before I throw out some pitches so you know where I'm coming from: I have travelled all over the world to include the USA. My preference, having lived near two major urban areas is to have a city nearby for cultural activities. I also want to be warm forever, so I am likely heading to the Tampa/St. Pete area which will give me the best of both worlds. If you now live in Hawaii, I have been there and would never go back. The place is way too expensive for what you get (Costa Rica is better) and living on an island would drive me crazy in no time.
If it is "cold" you want AND on the east coast, you'll have to be heading to NY State-Connecticut and north. Everything from NJ on south along the coast suffers from the same humidity levels as Florida and they don't get the benefit of the Gulf of Mexico's constant breeze. If New England, then you will lose the gulf stream and have no pleasurable ocean water temperatures to swim in. While New England has higher education rates, lower crime, and excellent cultural access, taxes are high, and the winters are VERY cold.
If you are looking for the perfect climate, we don't have it here in the US. San Diego is the closest we get, although you can't go in the ocean because Alaska sends all their cold water down the coast. If you want the perfect climate: Guatemala: land of eternal spring.
Live it up: There will be plenty of time to be old when you die.
