Douala in September

November through February offers the sweet spot — less rain, cooler temperatures, and clearer skies. Daily highs hover around 30°C instead of the brutal 35°C+ of dry season peaks. December gets busy with diaspora visits for holidays, so book accommodation early. March through May brings intense heat and humidity that'll melt your phone battery. June through October means rain. Not gentle European rain — proper tropical downpours that flood streets and shut down the city for hours. But here's the thing: rainy season has its charms. Hotel prices drop 30%, fewer crowds, and the city looks impossibly green. Just pack waterproof everything and accept that plans will change.
