About lightning in Brazil
Brazil is a world capital of lightning. The Amazon basin storms on a near-daily clock year-round, while the populous southeast — São Paulo, Rio de Janeiro, Belo Horizonte — sees its most intense activity in the wet season from October to March, when humid tropical air and urban heat fire violent afternoon thunderstorms. With some of the highest flash densities on the planet, the live distance to the nearest strike, and its trend, matter more here than anywhere.
