CDC Guidelines

Lightning is one of the leading causes of weather-related fatalities. But the odds of being struck by lightning in a given year are only around 2 in 1,000,000. However, some factors can put you at greater risk for being struck. Regional, seasonal, and occupational differences affect your risk of being injured by lightning.

  • Males are five times more likely than females to be struck by lightning; around 85% of lightning fatalities are men.

  • People aged 15–34 years account for almost half of all lightning strike victims (41%). The majority (89%) of lightning deaths occur among whites.

  • About one-third (32%) of lightning injuries occur indoors.

Outdoor Safety Tips

  • Don’t stay in open vehicles, structures, and spaces
    During a thunderstorm, avoid open vehicles such as convertibles, motorcycles, and golf carts. Be sure to avoid open structures such as porches, gazebos, baseball dugouts, and sports arenas. And stay away from open spaces such as golf courses, parks, playgrounds, ponds, lakes, swimming pools, and beaches.

  • Don’t stay near tall structures
    Do NOT lie on concrete floors during a thunderstorm. Also, avoid leaning on concrete walls. Lightning can travel through any metal wires or bars in concrete walls or flooring.

Indoor Safety Tips

  • Avoid water
    Do NOT bathe, shower, wash dishes, or have any other contact with water during a thunderstorm because lightning can travel through a building’s plumbing.

  • Avoid electronic equipment
    Do NOT use your computers, laptops, game systems, washers, dryers, stoves, or anything connected to an electrical outlet. Lightning can travel through electrical systems, radio and television reception systems, and any metal wires or bars in concrete walls or flooring. Equip your home with whole-house surge protectors to protect your appliances.

  • Avoid corded phones
    Corded phones are NOT safe to use during a thunderstorm. Do NOT use them. However, it is safe to use cordless or cellular phones during a storm.

  • Avoid windows, doors, porches, and concrete
    Do NOT lie on concrete floors during a thunderstorm. Also, avoid leaning on concrete walls. Lightning can travel through any metal wires or bars in concrete walls or flooring.
