West Africa is well known for Harmattan winds. The Harmattan wind is strongest from the end of November to March and is a very dry and very dusty trade wind that blows from the Atlantic Ocean across Africa. Harmattan trade winds also steer African sand westward across the Atlantic ocean into the Southeastern part of the USA and the Caribbean Sea.


Harmattan winds in West Africa are cold, dry, dust-laden winds. Harmattan wind temperature fluctuates from cold to temperate.
Humidity drops by 10 to 15 percent during the Harmattan season.


The dry dusty wind is capable of causing a variety of infrastructure troubles. This fine dust covers the entire atmosphere causing limited visibility comparable to heavy rain or snowstorm. This condition is called Harmattan haze.


A harmattan wind brings very dry weather conditions, lower humidity, scatters cloud cover, prevents rainfall formation and creates clouds of dust resulting in dust storms. These dust storms have grave medical consequence, as it consists of fine dust particles between 0.5 micrometers and 10 micrometers that is 17 times smaller than the width of a single strand of human hair.


The skin can become dry during Harmattan season as a result of the dry wind. When the skin is dry, it becomes wrinkled. The skin can also have cracks, which can degenerate into bruises. People especially sickle cell anemia patients also have the tendency to develop skin rashes during the season, which can also induce itching, whereby they may inadvertently introduce infections to the skin. People in West Africa breathe dry air dusty particles leading to an increased incidence of sneezing, nose bleeding, and cough, mucus, sore throat, as well as trigger attacks in asthmatic patients. 


In legend, the Harmattan season has a positive side since a severe Harmattan season means a fruitful harvest for fruit trees like mangoes, avocado, and guava. African countries with a Harmattan wind season are Nigeria, Central African Republic, Mali, Niger, Ghana, Benin, Senegal, and Burkina Faso.
