Climate

Timbuktu features a hot desert climate (BWh) according to the Köppen Climate Classification. The weather is extremely hot and dry throughout much of the year, with most of the city's rainfall occurring between June and September, due to the influence of the Intertropical Convergence Zone (ITCZ). The degree of diurnal temperature variation is higher in the dry season than the wet season. Average daily maximum temperatures in the hottest months of the year – April, May and June – exceed 40 °C (104 °F). Lowest temperatures occur during the mildest months of the year – December, January and February. However, average maximum temperatures do not drop below 30 °C (86 °F). These winter months are characterized by a dry, dusty trade wind blowing from the Saharan Tibesti Region southward to the Gulf of Guinea. Picking up dust particles on their way, these winds limit visibility in what has been dubbed the " Harmattan Haze." Additionally, when the dust settles in the city, sand builds up and desertification looms.
