Tropical. The dry season lasts from November to March and the rainy season from June to October. The best months are November to February when the Harmattan wind blows from the east producing dry and cool weather. However if you have allergies, avoid December to February as the Harmattan turns Burkina Faso into a dust bowl. Rainfall is highest in the southwest and lowest in the northeast. Avoid travelling in late March to May as the climate is too hot and dry to bear even for the locals.

Lightweights and rainwear for the rainy season. Plenty of scarves and handkerchiefs are recommended during the months when the Harmattan blows.
