--August is the last month of meteorological summer in the Northern Hemisphere, and of winter in the Southern Hemisphere. --By tracking the latest hours in white, the overhead sun can be seen moving east to west on a daily basis. --Thunderstorms travel west to east over the middle and higher latitudes in both hemispheres, and are stationary or move more slowly from east to west in the tropics. ~Ron Holle

Southern Hemisphere --The Andes provide a sharp western boundary in a NNW-SSE line and no lightning occurs over the cold water offshore of the Andes. --Recurring winter storms over the southern oceans move from west to east for long periods. --Australia has most of its August thunderstorm activity over the ocean to the south. --Thunderstorms over South America are limited to northern and western Brazil, the Guyanas, and occasionally over Uruguay. --Long lines of thunderstorms occasionally extend to the east and southeast from the southeast coasts of Africa, Australia, and South America. ~Ron Holle
