Traveller notes on Ouagadougou in May
Other months in Ouagadougou
Forum posters name the May-through-October stretch as Burkina Faso's more suitable, cooler season, with July falling within that window and bringing less intense sun along with a greener, blossoming Savanna landscape compared to the hotter dry season. Given how limited detailed destination-specific trip reports are for Ouagadougou on the forum, this note leans on that broader seasonal cue: July sits within the rainy season here, meaning real humidity and regular rainfall alongside the relatively cooler temperatures. Posters generally frame this wetter, greener stretch as a genuine trade-off - cooler and lusher than the peak dry-season heat, but with a real chance of rain-related disruption to travel plans. Posters generally rate the broader May-October window, July included, as a reasonable time to visit Ouagadougou.
Forum posters name May through October as Burkina Faso's cooler season with less intense sun and a greener, blossoming landscape - by inference, January sits outside that window in the hotter, drier dry season instead, when the Harmattan wind brings dusty, hazy conditions typical of the Sahel. One poster mentioned a successful December visit to Ouagadougou, suggesting the surrounding winter months remain workable despite the heat. Given the sparse detailed trip reports specific to Ouagadougou's January weather, this general Sahel dry-season pattern - hot, dusty days with essentially no rain - is the most reliable guide available for planning a visit this time of year.
