Get an Airport Facilities Directory. These green books have information on every airport in a their specific geographical area. These directories have all the information any pilot would need before departing to their destination, often including a telephone number to the automated ATIS. The ATIS will advise you of landing and departing runways for that hour at question.

Although I do not have an A/FD for GA I will be around one in the next couple of days, so if no one else here has one that they can post I will post the ATIS telephone # (if published) in a couple days.
