Nigeria is located in the tropics and has only two seasons. The Dry/Harmattan Season and the Rainy/Wet Season.
Dry / Harmattan
This season is accompanied by a dust laden airmass from the Sahara Desert, hence its name for Harmattan. During the harmattan season in Nigeria, wind blows in the north, provoking sandstorms, which sometimes impairs visibility. In the south, the sky in the mornings is often covered with a haze of fog.
The dry season in Nigeria isfrom November to March, especially in November and December. At this time, the weather on the coast (Lagos, Calabar) is still very hot, but the humidity is less when compared to the rest of the year. Moving to the north, the climate becomes drier and in the center of the country the days are sunnier, and the nights are colder (Jos). There is almost no rain in the north, and the day is hot, while the nights are cold (Kano, Maiduguri).
Explorers from the Saharan countries that are used to the hot weather can explore Nigeria during the dry season as transportation and movement around is considered better than in the rainy season.
Rainy / Wet
The airmass during this season originates from the southern Atlantic Ocean. The rainy season in Nigeria on the coast lasts for seven months (from the end of March to the end of October).
The rains are very intense along the coastal states. The rainiest place in the country is Calabar, where the rainfalls pour until December. There is a small “dry break” in August in the southern part of the country widely known as AUGUST BREAK. Heavy rains also occur in the center of the country, while in the north the season is limited to four months (from June to September). The sea in Nigeria is warm all year round, but swimming can be dangerous due to strong tides.
For explorers coming from a considerably coldcountry weather, it is advisable to explore Nigeria around the Rainy Season as the weather is considerably cooler and bearable.
