geopolitical zone of Nigeria
South West Nigeria is a region of Nigeria. It is mostly a Yoruba-speaking area, although there are different dialects even within the same state.
The weather conditions vary between the two distinct seasons in Nigeria; the rainy season (March - November) and the dry season (November - February). The dry season is also the bringer of the Harmattan dust; cold dry winds from the northern deserts blow into the southern regions around this time.
Intercity Lagos-Ibadan Railway trains operate several times per day between Lagos and Ibadan. The new higher-speed railway line is expected to be extended northwards during the early 2020s.
