Lightning is so common we barely think about it, but the global statistics are staggering. At any given moment, approximately 2,000 thunderstorms are active somewhere on Earth, producing about 100 lightning strikes per second — over 8 million per day, or 3 billion per year.
Each bolt heats the air around it to 30,000°C — five times hotter than the surface of the Sun. This sudden heating expands the air explosively, creating the shock wave we hear as thunder.
Lightning by the Numbers
- Speed: A bolt travels at about 300,000 km/s (the speed of light)
- Power: Up to 1 billion volts and 30,000 amps
- Length: Average bolt: 5–10 km. Record longest: 768 km across three U.S. states (2020)
- Strike density: Lake Maracaibo in Venezuela averages 250 lightning days per year — the highest on Earth
The Catatumbo Lightning
Above Lake Maracaibo, a phenomenon called the Catatumbo Lightning has been striking the same area for thousands of years — sometimes for 10 hours straight, with up to 280 strikes per hour. Sailors used it as a natural lighthouse for centuries.

Every time I see lightning now I'll think about the 99 strikes happening simultaneously elsewhere.
The Catatumbo Lightning is on my bucket list.
