Climate & Weather Guide
Climate zones, seasonal temperatures, rainfall patterns, and best travel times in Cameroon
Cameroon features a diverse climate gradient from equatorial rainforests in the south to semi-arid Sahelian conditions in the north, influenced by its position straddling the Gulf of Guinea and Lake Chad. Köppen classifications include Af (tropical rainforest), Am (tropical monsoon), Aw (tropical savanna), and Aw/BSh (hot semi-arid) transitioning northward. Recent data shows rising temperatures up to 36°C in northern regions and shifting rainfall patterns, with bimodal rain in the south (over 2000mm annually) and unimodal shorter wet seasons in the north (under 1000mm). Expats should prepare for high humidity in coastal and southern areas, intense dry Harmattan winds from December to February, and increasing heat extremes affecting urban living and agriculture.

Regional Climate Variations
Far North (Sudano-Sahelian)
The hottest and driest zone with hot semi-arid to savanna climate (Aw/BSh). Summers exceed 36°C with Harmattan winds bringing dust and cold nights around 18°C. Rainfall is low and unimodal (June-September), often below 800mm, leading to droughts and water scarcity. Recent bulletins warn of extreme heat and shifting rains impacting crops and livestock. Ideal for heat-tolerant expats but challenging due to aridity and sandstorms.
Intensely hot days with dusty Harmattan winds, cool nights, and prolonged dry spells creating a harsh, arid environment suited to resilient residents.
North and Adamawa (High Savannah)
Tropical savanna climate (Aw) with hot temperatures averaging 27-33°C year-round. Unimodal rains from May-October total 900-1200mm, but recent trends show erratic patterns and dry Harmattan seasons. Highlands moderate some heat, yet extremes reach 35°C. Agriculture dominates, vulnerable to heat stress and pests. Expats enjoy savanna landscapes but must adapt to seasonal water shortages.
Warm, sunny savanna with distinct wet-dry seasons, moderate humidity, and breezy Harmattan periods offering comfortable evenings amid grassy expanses.
Western Highlands
Elevated terrain (1000-2000m) creates a cooler tropical highland climate with temperatures 20-28°C. Bimodal rainfall (March-June, September-November) around 1500-2500mm supports lush vegetation. Recent data notes saturated soils and storm risks. Cooler nights appeal to expats from temperate zones, though fog and landslides occur in wet seasons.
Mild temperatures, frequent mists, and verdant hills providing a refreshing highland retreat with reliable growing seasons.
Centre and Littoral (Bimodal Forest)
Tropical monsoon climate (Am) in Yaoundé and Douala areas, with highs 28-32°C and oppressive humidity. Two rainy seasons deliver 1600-3000mm, punctuated by short dry spells. Urban heat islands amplify recent warming to 31-34°C. Coastal influences bring storms; expats face flooding but benefit from year-round greenery.
Humid, lush tropics with heavy downpours, vibrant biodiversity, and warm nights demanding good ventilation for comfortable living.
South and East (Monomodal Rainforest)
Equatorial rainforest (Af) with stable warmth 23-30°C and extreme rainfall exceeding 3500mm annually in one long wet season (March-November). Minimal dry period; recent shifts cause prolonged saturation and floods. Dense forests thrive, but high humidity and insects challenge expats. Mount Cameroon adds orographic rains.
Consistently warm, drenched rainforest ambiance with perpetual greenery, high humidity, and frequent rains fostering a steamy, immersive equatorial experience.
Cameroon's climate spans semi-arid heat in the Far North to perpetually wet equatorial south, with savanna and highland transitions offering varied options for expats. Recent trends of rising temperatures and erratic rains heighten adaptation needs, particularly in agriculture-dependent north. Coastal and southern humidity suits tropical lovers, while highlands provide milder relief for long-term residents.
