When people ask about the hottest country in the world, the answer isn’t just about one‑day extremes like Death Valley in the U.S. or the deserts of Kuwait. Instead, scientists look at average annual temperature and by that measure, Burkina Faso takes the crown.
This West African nation records year‑round averages close to 30 °C, making it the most consistently hot country on Earth. Unlike regions that only spike in summer, Burkina Faso’s climate is relentlessly warm across all seasons. Sahara winds, minimal rainfall, and abundant sunshine combine to trap heat and prevent cooling, creating a climate that rarely offers relief.
The geography of Burkina Faso plays a huge role in its extreme heat. Its proximity to the equator ensures intense solar radiation, while the influence of the Sahara Desert brings prolonged dry seasons. With little rainfall and scarce vegetation, the land absorbs and radiates heat, keeping temperatures high day and night.
Other countries such as Mali, Niger, Chad, and even Kuwait often enter the discussion, but none surpass Burkina Faso’s sustained heat across all regions. This distinction makes Burkina Faso not only a fascinating case for climate scientists but also a challenging environment for agriculture, water supply, and daily life.
