Catatumbo lightning, Meteorological phenomenon in Lake Maracaibo, Venezuela

Catatumbo lightning is a meteorological phenomenon over the southern basin of Lake Maracaibo in Venezuela, where the Catatumbo River empties into the lake. Cumulonimbus clouds rise 12 to 15 kilometres as warm, humid air from the lake is forced upward by the Perijá range and the Cordillera de Mérida. Discharges occur between cloud and ground and between clouds, mostly within the clouds, forming an arc 2 to 10 km high.

The phenomenon was first described in Lope de Vega's epic poem La Dragontea, published in 1597, which recounts Francis Drake's defeat by Diego Suárez de Amaya. For centuries it was known as Lanternas de Santo Antonio or Faroles de Maracaibo, and navigators used the flashes as a natural beacon. Alexander von Humboldt later described it as phosphorescent glows, and Agustín Codazzi called it a continuous lightning bolt.

The lightning appears on the flag and coat of arms of Zulia state, symbolizing the natural power and regional identity. Local communities have incorporated this spectacle into their sense of place and connection to the landscape.

The phenomenon is most active between April and November when viewing conditions are optimal. Visitors should seek elevated vantage points and plan to watch during evening and nighttime hours for the best experience.

This location holds a Guinness World Record for the highest concentration of lightning strikes on Earth with roughly 250 strikes per square kilometer. The consistent frequency of these electrical discharges makes it one of nature's rarest phenomena.
