If you look on a globe and see where UK is, follow that line across in USA and that's what the weather will be similar too. Obviously colder than what you are used to, and more rain, pretty cold at times in the winter with the odd bit of snow and can be hot in the summer.
I quite like Brighton. It's also not too far from London and also near to the rest of Europe if you fancy visiting there. Lots of people go on day/weekend etc trips by boat to France, Belgium etc
