Will be visiting BJ and surrounding areas from 2'-13 may What's the weather like?

Well, the temp difference is a little bit big in there. The highest temp would be about 84.2F, while the lowest would be 46.4F. In most of the days, it would be sunny or cloudy. So you may still need to take leather jacket and jeans for the morning and evening time would be a little bit cold. But in the afternoon, only a long sleeve shirt would be ok.
