Summer Safety

Thunderstorms and heat are commonplace in summer, and can pose a danger to hikers and other Appalachian Trail visitors.

Thunderstorms

The odds of being struck by lightning are low, but it can happen; if you become caught in a thunderstorm, the actions listed below can help lower the odds even more.

  • Immediately leave exposed areas, like open hilltops or balds. WARNING: Boulders, rocky overhangs, and shallow caves offer no protection from lightning, which may actually flow through them.
  • Avoid tall structures, such as ski lifts, flagpoles, solitary rocks, and the tallest trees.
  • Sheltering in hard-roofed automobiles or large buildings is best.
  • If you cannot enter a building or car, take shelter in an area of smaller trees or in the forest.
  • If caught in a clearing, crouch down on a pack or pad, or roll into a ball.
  • Disperse groups, so everyone is not struck by a single bolt.
  • Do not hold a potential lightning rod, such as a fishing pole or metal hiking pole.

HeatA hiker stays hydrated.

Dry, hot summers are common along the Trail, particularly in Georgia, the Virginias and the mid-Atlantic, where the combination of lower elevations and more southerly latitude typically make for the highest temperatures. Water may be scarce on humid days, sweat does not evaporate well, and heat stroke and heat exhaustion are real possibilities.

The actions listed below can help you avoid heat related problems.

  • Wear a hat and sunscreen.
  • Stay hydrated as you walk, and drink plenty of water at camp.
  • Watch for dark yellow urine, an indicator of dehydration. You are not drinking enough unless your urine is clear and copious.
  • Avoid hiking in the middle of the day and late afternoon when temperatures are highest.
  • Don’t push yourself.
