Leaving Virginia in early may and finishing in Seattle beginning of july what kind of low temperatures should I be expecting.
May in Virginia, West Virginia, Ohio, Indiana you can easily get 40s at night. Likely upper 40s. June in Illinois, Missouri, Kansas, east Colorado expect lows of 50s likely. Mountains, I'm not sure. It can easily freeze in the mountains, but you are not going to camp at the high elevations where the freezing and possible snow will occur. You will camp where it could get 40s maybe maybe 30s. June, July west of the Rockies, expect lows of 40s or 50s. To get the warmest weather, you should postpone your start date by one month. You're a little bit early and could get cooler weather. July and August are the hot months. Not May and June.
