Countries closer to the Earth’s equator (zero degrees latitude) experience warmer temperatures year-round in comparison to countries farther north or south of the equator. Countries that are further north in the Northern Hemisphere or south in the Southern Hemisphere generally experience four seasons and a wide range of temperatures, including significantly colder temperatures in the winter. There are several factors that influence this.
Because of the Earth’s tilt on its axis, the poles receive the sun’s rays at a slanted angle and the rays are spread over a much larger area. The equator, however, receives the rays more directly over a smaller area, making the rays more concentrated.
Other factors that are less significant but still contribute to hotter temperatures at the equator are the absorption and scattering of sunshine when passing through the atmosphere and reflection by the Earth’s surface. Higher latitudes have more air molecules and particles, resulting in greater absorption and less solar energy reaching the surface. Reflected energy from the sun bounces back and does not warm the Earth. The amount of rays reflected depends on the surface and snow reflects much of the sun’s energy, causing the already cold regions of the world to remain cold. Regions around the equator absorb a lot of the sun’s rays leading to warmer conditions.
This being said, the hottest countries in the world tend to be in regions close to the equator. The hottest countries are both land-locked, desert-covered nations and islands.
The ten hottest countries in the world are:
Burkina Faso is the hottest country in the world. The average yearly temperature is 82.85°F (28.25°C). Located in West Africa, the northern region of Burkina Faso is covered by the Sahara Desert. The country is susceptible to recurrent droughts, a serious problem for a nation that is consistently hot.
Below is a table of the hottest countries in the world and each of their average temperatures.
