Average Temperatures along the Appalachian Trail

Weather recording stations are not always near the Appalachian Trail. Where the A.T. is higher than the nearest recording station, subtract 3.5° per 1,000 ft. to approximate actual trail temperatures. Appalachian Trail guidebooks and maps include detailed elevation information. The higher the mountain, the colder, windier and wetter you can expect it to be.

High/low temperatures shown, in degrees Farenheit.
