Key Summary- Cameroon transitions from a perpetually humid equatorial rainforest (Af) along the coast to a hot semi-arid (BSh) far north, driven by the Gulf of Guinea and Saharan influences.
- The Cameroon Volcanic Line lifts the western highlands into cooler subtropical highland climates (Cfb), offering mild temperatures that break the tropical heat.
- Seasonality tightens as you travel north: the south has two rainy peaks, while the north endures a single intense wet season followed by a long, dusty Harmattan dry spell.
Cameroon sits at a climatic crossroads where the moist Gulf of Guinea meets the drying breath of the Sahara. Stretching from roughly 2°N to 13°N, the country’s geography imprints a vivid sequence of Köppen climate zones onto our WeatherBox maps. A narrow coastal belt anchored by Douala and Limbe sweats under an equatorial rainforest (Af) regime, with abundant rainfall and high humidity all year. Inland, the climate shifts through tropical monsoon (Am) and then tropical savanna (Aw) across the southern plateau and the Adamawa highlands, where a distinct dry season sets in. The far north around Maroua settles into hot semi-arid (BSh) territory, while the Cameroon Volcanic Line, crowned by Mount Cameroon and the Bamenda Grassfields, juts upward into highland subtropical (Cfb) air. Here, altitude chisels the heat away, producing pleasant daytime temperatures and noticeably cooler nights.
The rhythm of rainfall dictates what you will feel and see. Southern forests like those in Campo Ma’an and Lobéké bloom under a bimodal rainfall pattern, with long rains from March to June and shorter rains in September and October, separated by a drier interlude in July and August. The western highlands gather orographic moisture, wrapping Bamenda’s green hills in mist and feeding the lush tea plantations near the escarpment. Farther north, the Adamawa Plateau’s savanna sees a single wet season between May and October, and by November the landscape dries into golden grass. North of the Benue River, the Sahelian zone bakes under a brief, concentrated rainy window from June to September. By December, the Harmattan wind arrives from the northeast, bringing dust-laden skies but also a welcome drop in humidity. During this long dry period, wildlife concentrates around water holes in Waza National Park, making animal sightings easier under sunshine that can be dazzlingly clear after the haze settles.
Travel patterns slot neatly into these seasonal shifts. The most comfortable windows for the south and coast are the long dry months of December to February and the shorter dry break in July and August, when beaches around Kribi and Limbe enjoy lighter rainfall and bearable humidity. The central plateau shines brightest from November to February, with lower temperatures and rain-free days ideal for exploring cultural towns. The far north is best visited during the early dry season, November to February, before the heat intensifies; daytime highs can stubbornly top 40°C (104°F) from March through May, making that pre‑rain period punishing. Pack light, breathable fabrics as your base year‑round, but add a raincoat or umbrella for the south’s wet months and a fleece or light jacket for the highland evenings, where the air turns refreshingly crisp. Sunscreen, a wide‑brimmed hat, and sturdy footwear belong in every bag. Cameroon’s climate mosaic means you can almost always find a pocket of the country in its sweet spot.
