Porto-Novo in October

November through March gives you the best weather – dry, less humid, and temperatures that won't melt your brain. December and January are perfect if you can handle the harmattan winds that blow dust from the Sahara. The rainy season from April to October makes everything green but also brings flooding, mosquitoes, and humidity that feels like wearing a wet blanket. Some roads become impassable, and outdoor markets turn into mud baths. Cultural festivals happen year-round, but the Gelede mask ceremonies peak during dry season. The annual Egungun festival in January brings elaborate masquerades to the streets. Local celebrations don't follow tourist calendars – they happen when the community decides they should happen.
