Climate & Weather Guide in Ghana

Climate zones, seasonal temperatures, rainfall patterns, and best travel times

Ghana features a warm tropical climate throughout the year, influenced by its equatorial position and the harmattan winds from the Sahara. The country spans four main climatic zones, from humid rainforests in the south to drier savannahs in the north, with no true winter but distinct wet and dry seasons. Temperatures remain consistently high, averaging 24-32°C year-round, making it appealing for expats seeking perpetual warmth. Rainfall varies significantly from over 2000mm in the southwest to under 1000mm in the north, with high humidity in coastal and forest areas. Sunshine is abundant during dry seasons, though coastal fog can reduce visibility. Ideal for residents who adapt to humidity and seasonal rains, but northern heat requires precautions.

Regional Climate Variations

Southwestern Rainforest Zone

This wet equatorial region around Axim and the southwest coast experiences the highest rainfall in Ghana, exceeding 2000mm annually, with two rainy seasons peaking in May-June and September-October. Temperatures stay warm at 24-30°C year-round, with very high humidity making it feel muggy. Köppen Af (tropical rainforest) dominates, supporting lush vegetation but challenging outdoor activities during heavy downpours. Expats appreciate the consistent warmth but need mold-resistant homes and good drainage.

Summer:25-30°C
Winter:24-29°C
Very high rainfall

Lush, humid paradise with frequent heavy showers and minimal temperature variation, perfect for nature lovers but demanding for humidity-sensitive residents.

Southern Forest Zone

Encompassing Kumasi and central forests, this area has a tropical monsoon climate (Am) with 1200-1800mm rainfall, concentrated in two wet seasons. Daytime highs reach 28-32°C, cooling slightly at night to 22-25°C. High humidity persists, especially during rains from April to June and September to November. The zone transitions from rainforest to semi-deciduous forest, offering milder conditions than the southwest for urban living in Accra's outskirts.

Summer:26-32°C
Winter:23-30°C
High rainfall

Warm, sticky with reliable rains nurturing fertile lands, balanced for agriculture and comfortable city life with air conditioning.

Coastal Savanna Zone

Along the Gulf of Guinea including Accra and Cape Coast, this tropical savanna (Aw/As) area sees 800-1400mm rain, mostly May-July and October. Hot days of 28-33°C contrast with cooler nights around 23-26°C, moderated by sea breezes but high humidity (70-85%). Harmattan dust arrives December-February, slightly drying the air. BSh influences drier spots like Accra, ideal for beach living with urban amenities.

Summer:27-33°C
Winter:24-31°C
Moderate rainfall

Sunny beaches with sea breezes tempering heat, occasional storms, and dusty dry spells—vibrant for coastal expats.

Northern Savannah Zone

The drier north, including Tamale, features tropical savanna (Aw) to hot semi-arid (BSh) climates with 900-1200mm rain in a single May-September season. Intense heat peaks at 30-38°C in dry harmattan months (November-March), dropping to 20-25°C nights. Lower humidity (50-70%) makes it more tolerable than the south, though dusty winds challenge comfort. Suited for those preferring space and less rain.

Summer:28-35°C
Winter:22-36°C
Low to moderate rainfall

Hot, dry expanses with intense sun and cooling evenings, appealing for heat-adapted residents seeking savannah openness.

Ghana's tropical climates range from very wet rainforests in the southwest to hot, drier savannahs in the north, with consistently warm temperatures ideal for year-round outdoor living. Expats will find coastal areas most comfortable due to breezes, while northern heat demands adaptation. Variations offer choices from humid forests to sunny plains, enhancing appeal for diverse lifestyles.
