Lightning strikes are rare for any single person, but collectively they cause an estimated 24,000 deaths and 240,000 injuries worldwide every year. In the United States, roughly 40 to 50 people die from lightning annually, and several hundred more are injured. About 90% of people struck by lightning survive, though most are left with some degree of lasting disability.
Your Odds of Being Struck
The National Weather Service estimates the odds of being struck by lightning in any given year at roughly 1 in 1,000,000. Over an 80-year lifetime, those odds shorten to about 1 in 12,500. That sounds reassuringly small, but the number shifts dramatically depending on where you live, how much time you spend outdoors, and what you do for work or recreation. A roofer in central Florida faces a very different risk profile than an office worker in Oregon.
These odds also don’t account for “near strikes,” where lightning hits nearby and the electrical current travels through the ground or jumps from a struck object to a person standing close. When the Weather Service factors in the likelihood that someone you know will be struck, the odds tighten further, to roughly 1 in 1,250 over a lifetime.
Where and When Strikes Happen Most
Florida is the clear leader in U.S. lightning deaths, with 51 fatalities between 2016 and 2025. Texas follows with 21, then Alabama and North Carolina tied at 11 each, and Colorado at 9. Florida’s combination of warm, humid air, afternoon sea breezes, and a large outdoor recreation culture creates ideal conditions for both frequent thunderstorms and human exposure.
Timing matters as much as geography. More than 90% of lightning activity occurs between May and October, and the most dangerous window is between noon and midnight. Summer afternoon thunderstorms are the classic scenario: heat builds through the morning, storms fire in the afternoon, and people are caught outside at parks, beaches, golf courses, and sports fields.
How Lightning Actually Injures People
Most people picture a direct bolt from the sky, but that’s actually one of the less common ways lightning hurts someone. Ground current is responsible for a large share of lightning deaths and injuries in the U.S. When lightning hits the ground or a nearby object, the electrical discharge spreads outward along the surface. Anyone standing or, worse, lying on the ground nearby can have that current pass through their body. The risk increases if you’re lying down, because the current travels a longer path through your body (head to feet) compared to standing, where only the short distance between your feet is exposed.
Side flash is another common mechanism. Lightning strikes a tall object like a tree, and part of the current jumps to a person standing nearby. This is why sheltering under an isolated tree during a storm is one of the most dangerous things you can do outdoors. Contact injuries happen when you’re touching something that conducts the strike, like a metal fence, pole, or piece of equipment.
Indoor Risks Are Real
Being inside a solid building dramatically reduces your risk, but it doesn’t eliminate it entirely. Lightning can travel through plumbing, electrical wiring, and phone lines. The CDC recommends staying away from all running water during a thunderstorm, meaning no showers, no washing dishes, and no handwashing. Corded phones, computers plugged into outlets, and other wired electronics can also conduct a strike into your body.
Cell phones and cordless phones are safe to use as long as they’re not plugged into a charger connected to an outlet. Plastic plumbing may carry less risk than metal pipes, but the safest approach is to avoid all contact with plumbing until the storm passes. Stay away from windows, doors, and concrete floors or walls, which can contain metal reinforcement that conducts electricity.
What Survivors Experience
The 90% survival rate is encouraging, but “survival” often comes with a long list of complications. Lightning injuries primarily affect the nervous system, and many survivors deal with problems that aren’t visible from the outside. Common long-term effects include difficulty forming new memories and retrieving old ones, trouble multitasking, slower reaction times, chronic headaches that don’t respond to typical pain relievers, persistent ringing in the ears, balance problems, and disrupted sleep patterns. Some survivors initially sleep excessively, then shift to sleeping only two or three hours at a time.
Personality changes are among the most disruptive consequences. Survivors often describe increasing irritability, difficulty carrying on conversations, and a tendency to withdraw socially. Depression is common, partly from the neurological damage itself and partly from the frustration of no longer being able to perform tasks that used to come easily. Many survivors report embarrassment at forgetting people’s names, job responsibilities, or key information they once knew well. These delayed symptoms can emerge weeks or months after the strike, making them harder to connect to the original injury.
Global Differences in Lightning Risk
The worldwide toll of 24,000 deaths per year is not evenly distributed. Tropical regions with frequent thunderstorms, large rural populations, and limited access to sturdy shelter bear the heaviest burden. Parts of Africa and Asia report death rates that dwarf anything seen in the U.S. or Europe.
Zimbabwe, for example, has reported rates of 14 to 21 lightning deaths per million people per year. South Africa’s urban Highveld region sees about 6.3 deaths per million. In Southeast Asia, one coastal province in Vietnam recorded a rate of 8.8 deaths per million, and China’s Hainan province reported an estimated rate of 10.6 per million. For comparison, the U.S. rate is roughly 0.1 deaths per million. The gap comes down to building infrastructure, warning systems, and how much of the population works outdoors in agriculture without access to lightning-safe structures.
