Spring The most changeable month of the year is March; snow can fall
on any day, especially at higher elevations. Hikers are often caught
off-guard when a sunny day around 70ºF or a little more is followed
by a wet, bitter cold day. By mid to late April, the weather is moderate.
Summer Heat, haze, and humidity are the norm by mid-June. Much precipitation
comes from afternoon thundershowers.
Fall In mid-September, a pattern of warm, sunny days and crisp, clear nights often begins. However, cool, rainy days also occur. Dustings of snow may fall at the higher elevations in November.
Winter Days during this changing season can be sunny and 65°F. or snowy with highs in the 20s. In the low elevations, snows of 1" or more occur 1-5 times per year. So snow in the valleys is uncommon. At Newfound Gap, 69" fall on average. Lows of -20°F. are possible in the high country.
