We are in the early stages of planning a trip to climb Mt. Rainier. We will be traveling from the Northeast and want to maximize our chances of getting a good weather window. Understanding that anything can happen weather wise, would we be better to plan the trip for late May / June or a July / August trip? We are planning on the Emmons Glacier route via Camp Schurman, is this route usually still in good shape in later summer? Or are we better to do it earlier?
Any feedback would be appreciated.
