Probability of Dying from a Lightning Strike
1 in 138,849
Lifetime probability in US
The lifetime odds of dying from a lightning strike in the US are about 1 in 138,849, though being struck (and surviving) is more likely.
Lightning kills an average of about 20 people per year in the United States, resulting in lifetime odds of dying from a lightning strike of approximately 1 in 138,849. The odds of being struck by lightning (not necessarily fatally) in a given year are about 1 in 1.2 million, and over a lifetime approximately 1 in 15,300.
About 90% of people struck by lightning survive, though many suffer long-term effects including chronic pain, memory problems, personality changes, and neurological damage. Males account for about 80% of lightning fatalities, largely because they are more likely to be engaged in outdoor activities. Peak lightning months are June through August.
The most important safety rule is: "When thunder roars, go indoors." If you can hear thunder, you are within striking distance. Seek shelter in a substantial building or hard-topped vehicle. Avoid open fields, hilltops, isolated trees, water, and metal objects. If caught outdoors with no shelter, crouch low with feet together (do not lie flat). Wait 30 minutes after the last thunder before resuming outdoor activities.
