--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 move more slowly from varying directions in the tropics. ~Ron Holle

Northern Hemisphere --August lightning over Canada, China, Europe, Russia and the U.S. occurs in both large and small systems, clusters, and lines. --Daily thunderstorms are mostly stationary over the mountainous coastlines of Morocco, Algeria and Tunisia in August. --Over India, there is widespread lightning over the north and east, and less to the south and west. --Central America, Cuba, Florida, the Gulf of Mexico, and Mexico have very frequent daily lightning during all of the month. ~Ron Holle

Tropics --The southern edge of August lightning over Africa gradually moves south of the equator. --Every few days in August, a squall line develops near Ethiopia and moves westward to the west coast of Africa. --Over all but the eastern tip of Brazil, daily thunderstorms form, then move from the east. Individual storms do not travel far or survive into the next day. --The equatorial trough, also called the Intertropical Convergence Zone, is well defined over the Eastern North Pacific and increases in organization during August over the Atlantic near the African coast. It is nearly absent in the Indian Ocean. --The major islands and land areas of tropical Southeast Asia and the Americas have daily thunderstorms. --Daily lightning occurs along the southern and central Red Sea coastlines to the east over Yemen and Saudi Arabia, and to the west over Eritrea and Sudan. ~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. --Organized thunderstorm complexes form often over northern Argentina and Uruguay, then move eastward. --Long lines of thunderstorms move west to east over the Southern Indian Ocean off South Africa. --Australia and New Zealand has intermittent lightning to the southeast in August. ~Ron Holle
