One of the best things about visiting Nigeria in the winter is that it’s considered the country’s dry season. This makes a great time to visit Nigeria and participate in some of the festivals held during this time of the year. The first major Muslim festival of the year in Nigeria, Eid al Maulud, occurs in February. If you're looking for a great party, the month of December offers Calabar Carnival, which features music, dancing, and an array of other events.
