The best time to visit Touba Merina is during the dry season, which runs from November to May.
During these months, the weather is consistently warm and sunny, with very little rainfall. This makes it ideal for exploring the city's significant sites and enjoying outdoor activities without the interruption of heavy downpours or high humidity. Temperatures generally range from 25°C to 30°C, offering comfortable conditions for sightseeing.
For those planning to attend the Grand Magal of Touba, a major religious pilgrimage, the timing is specific and varies each year based on the Islamic calendar. This event typically falls within the dry season, often between September and November. If your visit is specifically for the Magal, it's essential to check the exact dates for your chosen year well in advance, as accommodations and travel can be heavily booked.
Visiting outside the dry season, from June to October, means you'll encounter the rainy season.
