What are the odds of being struck by lightning?

According to the Lightning Safety Council, the odds of being struck by lightning in a given year is 1-in-1.6 million.

Your odds depend on your behavior when lightning is in the area. If you always go indoors before lightning becomes a threat, your odds of being struck are almost zero, the council says.

How to stay safe around lightning

The CDC offers the following safety guidelines:

  • Go inside if you hear thunder or see lightning.
  • Avoid water during thunderstorms. Don't bathe, shower or wash dishes. Lightning can travel through a building's plumbing.
  • Don't touch electronic equipment or any metal wires or bars. Don't use anything connected to an electrical outlet such as computers, laptops, game systems, washers, dryers or stoves.
  • Stay away from window, doors, porches and concrete.
  • If you're outside, be aware of the forecast before heading out. Stay away from open spaces like golf courses, parks and playgrounds, and avoid open vehicles such as convertibles, motorcycles and golf carts.
  • Open outdoor structures like picnic shelters, tents, gazebos and baseball dugouts don't provide protection from lightning.
  • If you're caught outside with no safe shelter, get off elevated areas like hills and mountain ridges. Crouch down in a ball-like position with your  head tucked and hands over your ears. Never shelter under a tree or lie flat on the ground. Get away from bodies of water.
  • Don't leave your pet outdoors during a thunderstorm.
