Burkina Faso flagClimate & Weather Guide

Climate zones, seasonal temperatures, rainfall patterns, and best travel times in Burkina Faso

Burkina Faso features a dry tropical climate dominated by hot savanna conditions, with a short rainy season from May to September and a prolonged dry season influenced by harmattan winds from the Sahara. Annual temperatures average 27-30°C, ranging monthly from 15-45°C, with higher extremes in the north. The country divides into three climatic zones: arid Sahel in the north (<600mm rain), central North-Sudanian (600-900mm), and wetter South-Sudanian (>900mm). Rainfall is highly variable and unpredictable, posing challenges for residents. Köppen classifications are primarily hot semi-arid (BSh) and hot desert (BWh) in the north, transitioning to tropical savanna (Aw) southward. Expats should prepare for intense heat, dust, and water scarcity outside the rainy period.

Regional Climate Variations

Northern Sahel

The northern Sahel zone experiences the harshest conditions with very low rainfall under 600mm annually, fitting hot desert (BWh) and hot semi-arid (BSh) Köppen types. Temperatures soar to 45°C in the hot season (March-May), with dry harmattan winds bringing dust and discomfort. Winters remain warm at 20-30°C, but the short rainy season (June-September) is unreliable. Residents face frequent droughts, high evaporation, and limited vegetation, ideal for hardy pastoralism but challenging for comfort without air conditioning and water management.

Summer:35-45°C
Winter:20-30°C
Very low rainfall

Extremely hot and arid with relentless dry winds; prepare for dust storms and water shortages year-round.

Central Sudan-Sahel

This transitional central zone receives 600-900mm of rain yearly, classified as hot semi-arid (BSh) to tropical savanna (Aw). The rainy season brings moderate relief, but dry periods dominate with temperatures averaging 28-38°C in summer and 18-32°C in winter. Variability in precipitation supports savanna grasslands, yet droughts and floods alternate unpredictably. Expats in cities like Ouagadougou encounter urban heat islands amplifying discomfort during peak heat.

Summer:32-42°C
Winter:18-32°C
Low to moderate rainfall

Hot with sporadic heavy rains; dusty dry season transitions to muggy wet periods, demanding adaptive cooling.

Southern Sudan-Guinea

The southern region enjoys the highest rainfall over 900mm, under tropical savanna (Aw) Köppen climate, with a longer rainy season fostering denser vegetation and agriculture. Summer highs reach 35°C with high humidity, while winters are milder at 17-30°C. Though wetter, rainfall remains erratic, and heat persists. This zone offers relative greenness but still requires vigilance against malaria and flooding for residents.

Summer:28-38°C
Winter:17-30°C
Moderate rainfall

Warm and humid with greener landscapes; wet season brings relief from dust but increases mosquito activity.

Burkina Faso's climate spans hot desert and semi-arid north to tropical savanna south, with extreme heat (up to 45°C), variable low-to-moderate rainfall, and long dry seasons defining daily life. Expats value abundant sunshine but must adapt to dust, heatwaves, and water insecurity using modern amenities. The diversity allows choosing drier north or wetter south based on tolerance for aridity.
