In Ghana's urban areas, like Accra and Kumasi, floods are mostly triggered by seasonal rainfall combined with poor drainage, the dumping of waste into waterways and the low elevation of settlements. In northern Ghana, some floods are caused by spillage from a dam in Burkina Faso.

The floods expose communities to health risks, food shortages and mental stress.
