The Harmattan is a dry and dusty trade wind that occurs in West Africa, typically between late November and mid-March. It originates from the Sahara Desert and brings cooler temperatures and low humidity to the region. The winds can carry fine dust particles, reducing visibility and affecting air quality. During the Harmattan season, people often experience dry skin and respiratory issues due to the dust. The phenomenon also influences local agriculture, as the cooler temperatures can benefit certain crops while posing challenges for others. Overall, the Harmattan plays a significant role in the climate and environment of West Africa.
