The best time to go to Gaoua is during the dry season, specifically from November to February.
During these months, the weather is more comfortable, with lower humidity and cooler temperatures, making it ideal for exploring the region. You'll find it easier to visit local markets, historical sites, and cultural attractions without the intense heat and rain that characterise other times of the year.
This period is particularly good for cultural travellers and those interested in local traditions. Many festivals and ceremonies of the Lobi people, such as the Gaoua Museum's annual events, often take place during the dry season, offering a more authentic experience. It's also a great time for outdoor activities, like visiting the archaeological sites of Loropéni, as the roads are more accessible.
While the dry season is generally more pleasant, it's worth noting that evenings can still be cool, so a light jacket or jumper is advisable.
