Climate & Weather Guide
Climate zones, seasonal temperatures, rainfall patterns, and best travel times in Nigeria
Nigeria, located in West Africa, features a predominantly tropical climate with significant north-south variations due to its large size (923,768 km²) and topography. The south is dominated by tropical rainforest and monsoon climates with high rainfall and consistent warmth, while the center transitions to savanna with distinct wet and dry seasons, and the north experiences hot semi-arid conditions with low rainfall and extreme heat. Average temperatures range from 21°C to 35°C year-round, with minimal seasonal variation but pronounced differences in precipitation. Residents and expats should prepare for humid coastal areas, dusty harmattan winds in the dry season (November-March), and heavy rains from April to October in the south. Recent data (1991-2020) confirms these patterns amid rising temperatures from climate change.[3][5]

Regional Climate Variations
Southern Coastal Zone
This equatorial region along the coast and up to 150km inland features Tropical monsoon (Am/Af) climate with very high rainfall exceeding 1500-2500mm annually, peaking in June and September. Temperatures remain consistently warm at 25-32°C year-round, with high humidity making it feel hotter. Wet season lasts 8-9 months, supporting rainforests but causing flooding risks for residents. Dry season is short and mild. Ideal for expats tolerant of humidity, but air conditioning is essential in urban areas like Lagos and Port Harcourt.[1][2][3]
Oppressively humid with frequent heavy downpours; lush greenery year-round but prepare for flooding and mosquito-prone conditions.
Central Savanna Zone
Covering much of Nigeria's interior, this Tropical savanna (Aw) area has bimodal rainfall of 1000-1500mm, with peaks in May-July and September-October, followed by a 4-month dry season. Temperatures average 26-34°C, cooler at night. Harmattan winds bring dust and lower humidity in the dry period. Cities like Enugu and Abuja experience moderate flooding risks. Suitable for expats preferring seasonal variety, with comfortable evenings but hot days requiring hydration.[1][2][3]
Distinct wet-dry seasons with refreshing harmattan breezes; savanna landscapes thrive, but dust storms can affect respiratory health.
Northern Semi-Arid Zone
The Sahel-influenced north features hot semi-arid (BSh) climate with low rainfall of 250-800mm in a short May-September season. Extreme heat reaches 35-42°C in dry months, with harmattan winds exacerbating dryness. Nights cool to 20°C. Areas like Kano and Yola face drought risks and heatwaves, as seen in 2019-2020 records. Expats need robust cooling and water management; agriculture relies on rainy season.[1][2][3]
Intensely hot and dry with scorching days; short rains bring relief, but persistent aridity demands sun protection and hydration.
Jos Plateau (Montane)
Elevated central highlands around Jos offer a cooler montane variant within savanna zones, with moderate rainfall of 1000-1400mm and temperatures 18-28°C due to altitude (1200m+). Less humid than lowlands, with misty mornings and comfortable days. Dry season is dusty but milder. Appeals to expats seeking respite from lowland heat, though fog and erosion are concerns.[1]
Pleasantly cool highlands with fresh air; ideal retreat from tropical heat, featuring rolling hills and moderate weather.
Nigeria's climate spans tropical monsoon in the wet south, savanna in the center, semi-arid north, and cooler montane plateaus, offering diverse experiences from humid coasts to dusty interiors. Expats will appreciate the warmth year-round but must adapt to intense rainy seasons, harmattan dust, and heatwaves. Coastal and highland areas suit humidity-tolerant residents, while savanna zones balance variety for long-term living.
