Significant flooding affected Nigeria last week, with more than 150 deaths reported so far. Heavy rain struck the north of the country on Wednesday night and continued into Thursday, leading to flooding along the Niger River, displacing thousands and destroying hundreds of homes. The district head said it was the region’s worst flood in 60 years.
Heavy rain is not unusual at this time of year in Nigeria. The country has a tropical climate and is influenced by the west African monsoon, with the wet season running from April until October. This type of seasonality is linked to land-sea temperature differences, alongside the shifting intertropical convergence zone (ITCZ), a band of low pressure roughly around the equator that shifts north and south with the angle of the sun.
