--June is the first month of meteorological summer in the Northern Hemisphere, and of winter in the Southern Hemisphere. --Thunderstorms in tropical regions primarily move from the east, while they move from the west in the southern portion of the map. --Lightning typically occurs during daylight hours over Africa. --The southern boundary of thunderstorms over mainland Africa is usually at, and north of the Equator during June. --Every few days in June, a squall line develops near Ethiopia and moves westward to the west coast of Africa; these systems become tropical waves over the Atlantic. --The equatorial trough over the Atlantic is weakly defined by lightning between the Ivory Coast and northeast Brazil. The trough is diffuse over the Indian Ocean. --Southern Africa, Madagascar, the Sahara, and South Atlantic are usually free of lightning. --Daily lightning occurs along the southern Red Sea coastlines. ~Ron Holle
