Lightning never strikes the same place twice
Lightning frequently strikes the same location multiple times, often repeatedly during a single storm. Tall structures such as the Empire State Building are struck roughly 25 times per year. The old saying is a figure of speech about rare fortune, not an accurate statement of atmospheric physics.
What we know
The saying "lightning never strikes twice in the same place" is typically used figuratively, to suggest that an unlikely event will not repeat itself for the same person or place. As a literal claim about atmospheric electricity, it is straightforwardly false, and meteorologists have documented this repeatedly using both direct observation and instrumented lightning-strike monitoring networks.
Lightning follows the path of least electrical resistance between a charged region of a storm cloud and the ground, and tall, prominent, well-grounded structures are disproportionately likely to provide that path on multiple occasions, sometimes even within the same storm system. The Empire State Building in New York City is the most frequently cited real-world example: monitoring data collected over decades shows it is struck by lightning approximately 23 to 25 times per year on average, with some individual storms producing multiple strikes to the building within just a few minutes. Photographic and video documentation of the Empire State Building being struck multiple times during a single storm event is extensive and has been publicly available for decades, making this one of the more directly falsifiable weather myths.
The physical explanation lies in how thunderstorms build up and discharge electrical charge. As a storm cloud develops, friction between ice crystals and water droplets within it separates electrical charge, typically leaving a negative charge concentration in the lower part of the cloud and inducing a positive charge in the ground below. When the resulting electric field becomes strong enough to overcome the insulating properties of air, a lightning discharge occurs along the most conductive available path, and tall, isolated, or well-grounded objects such as skyscrapers, radio towers, lone trees on open ground, and mountaintops consistently offer lower resistance than the surrounding terrain. Because this favorable path exists as a persistent physical feature of the landscape, not a one-time fluke, the same structure can be struck repeatedly across many storms over its lifetime, and even multiple times within a single storm as the cloud rebuilds and redischarges its charge separation.
Lightning rod technology, invented by Benjamin Franklin in the 18th century, works by deliberately exploiting this same physical principle: a grounded metal rod placed at the highest point of a structure provides an intentionally low-resistance path for lightning to follow, safely conducting the discharge into the ground rather than through the building's structure or occupants. The routine, expected, and repeated use of lightning rods on tall buildings is itself indirect proof that engineers assume, correctly, that the same structure will be struck again and again over time, which is precisely why the protective measure is built in as permanent infrastructure rather than a one-time precaution.
The National Weather Service and other meteorological authorities note that certain geographic areas, including parts of Florida and other regions with frequent thunderstorm activity, see so many lightning strikes per square kilometer annually that the same exact ground location, not just tall structures, is statistically likely to be struck more than once over sufficiently long timeframes. Studies using ground-based lightning detection networks confirm that recurrence at high-risk points, particularly elevated or isolated terrain features, is common and expected rather than exceptional, reinforcing that the popular saying should be understood strictly as an idiom about improbability in everyday life, not a scientifically accurate description of how lightning behaves.
