In Benin, flooding has affected the districts of Athiémé, Grand-Popo and Lokossa in Mond department. In Athiémé, flooding has affected 31,482 people from 9,258 households. Roads and public buildings have been flooded. Four health centres in the area are inaccessible after flood water blocked roads.

Sixteen villages in Grand-Popo are flooded, affecting 994 households. In Lokossa around 2,500 households in the communities of Lokossa and Ouèdèmè-Adja are affected.
