Lightning Storms: 7 Safety Tips

I love watching lightning—nature’s light shows—but, yes, it can be dangerous. Here’s some background on lightning and basic lightning safety rules.

Lightning strikes more than 40 to 50 times a second during June, July and August. What you are watching are spectacular electric sparks. Just as you build up static charges when you shuffle your feet along a carpet, so the collision of ice and slush churning in a thundercloud builds up charges. The slush near the bottom of the cloud builds up a negative charge while the tiny ice crystals carried to the top become positive. Finally, the charges equal out, just like that irritating spark that stings you when you touch something. The charge flows somewhere and about 25% of the time—BANG!—it hits the ground.

That’s where it can get dangerous. But some places are more dangerous than others.

  • Kifuka in the African Democratic Republic of the Congo averages 410 lightning strikes per square mile every year.
  • In North America, the champion is the Tampa-Orlando area with 91 flashes per square mile.

Even then, statistics show that not all people face the same risks. Little old ladies are safe, but guys between the ages of 20 and 30 seem to be lightning rods.

Safety in Lightning Storms

The rules for safety in lightning storms are basic.

  • Be smart enough to get out of the rain if you hear thunder.
  • If you are outside, avoid being the highest object anywhere—or taking shelter near or under the highest object, including tall trees. Better to crouch down in an open field than stay near trees.
  • Cars are relatively safe shelters. Make sure the windows are shut.
  • If you are with other people in a lightning storm, stay about 15 feet away from each other.
  • Obviously, stay out of water!
  • Avoid metal, even metal on a purse or backpack.
  • Remember, the 4th of July is historically one of the most deadly times of the year for lightning in the U.S.
