Overview of Nigeria's Climate
Nigeria experiences a predominantly tropical climate, varying from equatorial conditions in the south to arid climates in the north. The country is divided into three main climatic zones: the humid coastal region, the tropical savanna in the central area, and the semi-arid northern region. Understanding these zones is essential for planning any relocation or travel within the country.
The wet and dry seasons are primarily influenced by the intertropical convergence zone (ITCZ), which brings moisture-laden winds from the Atlantic Ocean, resulting in significant rainfall during the wet season. Conversely, the dry season is marked by the harmattan winds blowing from the Sahara Desert.
January - March: The Dry Season
January
January is typically characterized by dry weather across Nigeria, with average temperatures generally ranging from warm to hot. In cities like Lagos, humidity levels can be high, making the heat feel more intense. The harmattan winds may bring a dusty haze, particularly in the northern regions.
For expatriates relocating to Nigeria, this is a good time to explore outdoor activities before the heat peaks. Ensure to stay hydrated and wear light clothing.
February
February continues the dry conditions with slightly higher temperatures in many regions. The harmattan conditions may persist, especially in northern Nigeria, creating a cooler atmosphere at night.
This month is ideal for exploring Nigeria's cultural sites and engaging in outdoor activities, but it is crucial to apply sunscreen and wear protective clothing against the sun.
March
By March, the weather begins to transition towards the wet season, particularly in southern Nigeria. Average temperatures remain high, generally reflecting the warm conditions typical of this time of year. In the northern regions, the harmattan winds start to dissipate, leading to rising humidity levels.
As the weather begins to change, expatriates should prepare for the upcoming rainy season by ensuring that their homes are equipped for potential flooding. Importantly, check that drainage systems are clear and functional.

May
May is one of the wettest months of the year, especially in the southern regions. Lagos experiences significant rainfall during this month. In central Nigeria, cities like Abuja start to receive substantial rainfall, leading to lush green landscapes.
Safety considerations during this period include being mindful of potential flooding, especially in low-lying areas. Expatriates should keep an eye on weather forecasts and avoid unnecessary travel during heavy rain.

July - September: Peak Wet Season
July
July is typically the peak of the wet season, with rainfall reaching its highest levels in southern Nigeria. Temperatures remain cooler due to cloud cover, contributing to a more comfortable atmosphere.
