Dedougou's climate is characterized by a long dry season and a short rainy season. The dry season typically begins in October and lasts until May, with temperatures gradually increasing during these months, peaking at an average of 30°C in March and April. During this time, the region experiences little to no rainfall, with some occasional thunderstorms in June that signal the start of the rainy season. The rainy season is short-lived, lasting only from June to September, bringing relief from the dry conditions but also heavy downpours that can cause flash flooding. As the rainy season comes to an end, temperatures begin to drop, paving the way for another cycle of hot and dry weather.
