June 17, 2026 · The Clime Team

Lightning strikes pose a significant risk across the United States, with approximately 40 million strikes hitting the ground annually. (cdc.gov) While the odds of being struck in a given year are less than one in a million, certain activities and regions can increase your risk. Understanding and implementing effective lightning safety measures is crucial to minimize these risks.

What Are the Primary Risks Associated with Lightning Strikes?

Lightning can cause injuries and fatalities through several mechanisms:

Direct Strike: A direct hit by lightning, though rare, is often fatal.
Contact Injury: Touching an object that lightning strikes, such as a metal pole or vehicle.
Side Flash: Lightning jumps from a struck object to a nearby person.
Ground Current: Electricity travels through the ground from a nearby strike, affecting individuals standing or lying on the ground.
Streamers: Electrical discharges from the ground can travel upward, causing injury.
Blast Injury: The explosive force of lightning can cause physical trauma.

Understanding these risks is the first step in effective prevention.

How Can You Protect Yourself Indoors During a Thunderstorm?

When indoors, follow these guidelines to stay safe:

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. (cdc.gov)
Stay Away from Electronics: Avoid using corded phones, computers, and other electronic equipment connected to electrical outlets. (cdc.gov)
Stay Away from Windows and Doors: Keep away from windows and doors, and stay off porches. (cdc.gov)
Avoid Concrete Floors and Walls: Do not lie on concrete floors or lean against concrete walls during a thunderstorm. (cdc.gov)

What Are the Safety Measures for Outdoor Activities?

If you find yourself outdoors during a thunderstorm, take immediate action:

Seek Shelter: Move to a substantial building or an enclosed metal-topped vehicle with the windows up. (weather.gov)
Avoid Isolated Trees: Do not shelter under isolated trees, as lightning tends to strike the tallest object. (fs.usda.gov)
Stay Away from Water: Get out of and away from ponds, lakes, and other bodies of water. (fs.usda.gov)
Avoid Electrical Appliances: Do not use electrical appliances during a thunderstorm. Cell phones, laptops, and devices that aren’t plugged in are okay. (tdi.texas.gov)

How Can You Protect Your Home from Lightning Strikes?

While you can't prevent lightning strikes, you can minimize potential damage:

Install a Lightning Protection System: A home lightning protection system can help disperse a lightning strike's electrical charge to the ground and not your home. (progressive.com)
Use Surge Protectors: Equip your home with whole-house surge protectors to protect your appliances. (cdc.gov)
Maintain Trees: Trim trees near your home to reduce the risk of them being struck and causing damage.

What Are the Regional Considerations for Lightning Safety?

Certain areas in the U.S. are more prone to lightning strikes:

Southeastern States: States like Florida and Texas have the largest number of lightning-related deaths. (cdc.gov)
Mountainous Regions: Elevated areas are more susceptible to lightning strikes. (fs.usda.gov)

Being aware of your region's lightning risk can help you take appropriate precautions.

What Should You Do if Someone Is Struck by Lightning?

If you witness a lightning strike, follow these steps:

Call Emergency Services: Immediately call 911 for help. (cdc.gov)
Administer First Aid: If the victim is not breathing, perform CPR. (cdc.gov)
Ensure Safety: Move the victim to a safe location, as lightning can strike the same place twice. (cdc.gov)

How Can You Stay Informed About Lightning Risks?

Staying informed is key to lightning safety:

Monitor Weather Updates: Carry a NOAA radio or visit weather.gov for weather updates. (fs.usda.gov)
Check Forecasts: Before participating in outdoor activities, check the weather forecast to be aware of potential thunderstorms. (cdc.gov)

By understanding and implementing these safety measures, you can significantly reduce the risks associated with lightning strikes.
