Weather Overview

Nigeria is located just above the equator and as such is generally hot all year round and experiences very minor variations in temperature. It is very humid and tropical in the South, and dry and hot in the north. Temperature stays high all year round.

In South of Nigeria the hottest months are usually February to April, while in North of Nigeria this tends to be from March to June. Harmattan months are the cooler months across the country and are from October to January, when dry winds from the northern sahara regions blow across the whole country.
 

Nigeria typically experiences two seasons, a wet and dry season, with a short break in between each season. In the south the rainy season starts around March and lasts for about four months until July. The rains during this season can be very heavy and it can rain non-stop for days. This is a period when roads get flooded, roofs leak, and movement and travel in general becomes more challenging. During the months of August to September the south can experience a few weeks of little or no rain usually refered to as the August Break, followed by more rain although very light in its nature. From October  to March the dry season kicks in with the onslaught of the harmattan winds bringing in dry winds and dust from the Sahara. During this season there is reduced moisture in the air, which in turn affects the vegetation growth within the region. 

Due to the hot weather, you should pack lightweight clothings that can be hand-washed. Whereas, for the rainy season, we recommend that you pack an umbrella with you and some rain-boots/Wellingtons because in some places it could rain for a whole week non-stop. During the harmattan season, you would need some long sleeved clothes/jackets as there could be intense cold in the mornings and nights most especially in the Northern parts.
 
In the north the two seasons are more defined with none of the breaks experienced in the South. Also in the North the wet season runs for a shorter period of time than in the South. The wet season in the North runs from June to Septmber, the rains are characterised as being heavy but last for shorter durations. The dry season in the North runs from October to May, the dry winds from the sahara ensures that the North experiences mainly dry conditions, and the harmattan winds that blow over the country from October to March ensure that the North dries longer. During this period there is very little cloud cover.
 
The most popular time to visit Nigeria is between November and May before the rainy season. Also, if you intend to visit game reserves and see more wildlife it would be best to visit at this time when the grasses are all dried out and animals move out to the river banks.
