The Hottest Continent
Africa is the hottest continent on Earth. While individual hot days can happen anywhere, Africa stands out because it is consistently warm across almost its entire area, all year round. No other continent holds as much land in the planet's hottest zones.
It's All About Position
The reason comes down to where Africa sits on the globe. The Equator runs right through the middle of the continent, and most of Africa lies within the tropics — the warm band of the Earth that receives the most direct, intense sunlight throughout the year. Because the Sun's rays strike this region so directly, temperatures stay high in nearly every season. Only the far northern and far southern edges of Africa escape this and have milder, Mediterranean-style weather.
A Continent of Deserts
Africa's heat is made even more extreme by its deserts. A huge share of the continent is covered by dry land, including the Sahara — the largest hot desert in the world. Deserts heat up dramatically under the strong tropical sun because there is little moisture or vegetation to soften the temperature. Some of the highest air temperatures ever recorded anywhere on Earth have been measured in these African desert regions.
