Harmattan is a season that occurs in West Africa when dry, dusty winds blow from the desert. It mostly affects the North East Region from December to March.
When dust blows in, it can linger for couple days or as long as few weeks. It greatly affects visibility and can cause breathing issues for some. One positive aspect is that the dust brings cooler temperatures!
The video below was shot in northern Ghana in the same location and the same time of day. However, there is four months’ difference between the rainy season shot and dry season shot.
