Climate of Nigeria

The climate of Nigeria is mostly tropical, with temperatures usually between 21 °C and 35 °C. The country has three main climatic zones and two seasons: a rainy season and a dry season. What the weather is like depends mostly on how close the land is to the sun and how clear the air is, which changes with how much rain falls and how much moisture is in the air.

Rain in Nigeria comes in three ways: from warm air rising, from weather fronts moving in, and from mountains that make rain. The rainy season is very important for farming because that is when most crops are planted and grow. The dry season can be hard because there can be droughts, which mean not enough water and sometimes crops do not grow.

Nigeria’s weather affects many parts of life, including farming, work, and health. The country is in West Africa, between latitudes 4°N and 14°N, and longitudes 2°E and 14°E, and this location helps decide what the climate will be like. The mix of different air masses and the shape of the land also play a big role in Nigeria’s changing weather patterns.

Climate of the country

Nigeria has three main climate zones, and it is mostly tropical. These zones are the tropical monsoon climate in the south, the tropical savannah climate, and the Sahelian hot and semi-arid climate in the north. Rainfall and temperature are important for Nigeria's climate, but rainfall is especially important for farming.

The tropical monsoon climate is found in the far south. This area gets a lot of rain each year, about 2,000 mm (6.6 ft). In the dry season, temperatures at night can be around 23 °C (73 °F), and during the day around 31 °C (88 °F). Places like Port Harcourt, Delta, and Bayelsa have this climate.

The tropical savannah climate, also called the tropical wet and dry climate, has both wet and dry seasons. The rain each year is about 1,200 mm (3.9 ft) or less. Nighttime temperatures are around 22 °C (72 °F), and daytime temperatures around 33 °C (91 °F). Lagos State is one example, and many central and southern areas also have this climate.

The Sahelian hot and semi-arid climates are found in the north. Daytime temperatures can reach 35 °C (95 °F), and nighttime temperatures are about 21 °C (70 °F). These areas get very little rain, less than 700 mm (2.3 ft) each year. States like Kaduna, Jigawa, and Sokoto are examples.

Climatic Zones of the Country

Nigeria has five main climate areas. These are the Sahel Savannah, Sudan Savannah, Guinea Savannah, Tropical Rain Forest, and the Coastal Climate. Each of these areas has its own weather patterns and conditions.

Seasons

Nigeria has two main seasons each year: dry and wet.

The dry season, from October to April, brings dusty winds and less rain. Temperatures can get very hot, sometimes up to 100 °F (38 °C). During this time, there is more sun and less moisture in the air. The harmattan wind often blows from December to January. The year 1983 was the driest year Nigeria has recorded since 1981.

The wet season, also called the rainy season, runs from April to September. It is especially rainy along the southeastern coast, where about 130 inches (330 cm) of rain can fall each year. Temperatures here usually stay below 90 °F (32 °C). The year 2019 was the wettest year Nigeria has recorded since 1981.

Temperature

Nigeria has warm weather all year because it is close to the equator. The temperature usually stays between 25 °C and 32 °C, but it can change a little depending on where you are in the country.

The hottest time of year is usually from February to April. In the south, temperatures can reach about 40 °C, while in the north they can get even hotter, around 43 °C. In 2021, Nigeria had some of the warmest temperatures ever recorded.

Examples

Nigeria has a tropical climate with three different climate zones and two main seasons. The temperature usually stays between 21 °C and 35 °C. What affects the temperature are how close Nigeria is to the sun and how clear the sky is, which depends on rain and humidity. Rain in Nigeria comes from three main reasons: warm air rising, weather fronts, and mountains shaping the weather.

Climate change

Over the years, Nigeria has faced more dangers because of changes in the weather. Places in the south and near the coast may flood because the ocean is rising. They also face risks from water illnesses. In the north, states are getting hotter, receiving less rain, and dealing with dry spells, which can lead to hunger and not enough food.

Nigeria joined the UN Environment's Climate and Clean Air Coalition in 2012 to help lower harmful substances in the air. The country promised to cut down on certain gases by 45 percent by 2030 after joining the Paris Agreement. In November 2021, Nigeria passed the Climate Change Bill, showing its goal to reach net zero emissions sometime between 2050 and 2070.

Extra

Nigeria has warm weather most of the year, with average temperatures between 21 °C and 35 °C. The northern part of the country gets especially hot, sometimes reaching temperatures above 35 °C. In 2019, some northern areas, like Minna, reached very high temperatures of around 42 °C.

During the rainy season, heavy rains can cause flooding in many parts of the country. In 2012, Nigeria had very severe flooding that affected many people. Flooding also happened in other years, such as in 2017 in Benue state and in 2021 in many parts of the country.

Nigeria also faces problems with long periods of little rain, called droughts. These droughts can harm farming and cause difficulties for people who depend on the land.
