A nasty grey sky was the first thing I spotted when opening the curtains on my very first morning in Cotonou. Was it going to rain any minute? A quick check of the weather app said „low visibility due to dust“. Eventually it sank in, Harmattan season. This wind bis lowing from the Sahara across West Africa between December and March fills the air with thick dust. The horizon is greyish white, a photographer’s nightmare. A kind of blue skies would sometimes reappear late afternoon.
