South America's largest body of water, Lake Maracaibo in Venezuela, is the site of "the most frequent lightning in the world", according to Graeme Anderson, an expert on the subject at the Met Office. This year Venezuela's Catatumbo Lightning was approved for inclusion in the 2015 edition of Guinness World Records.
The heat and humidity are at optimum levels here, and with the addition of wind caused by the surrounding Andes, the lightning is the most intense and predictable in the world.
Spectacular storms are a crowd-pleaser, and apparently something people are prepared to pay to see. Lakeside fishing communities now welcome tourists who come on special trips from Mérida, a lively Andean town in the north-west of the country.
