Scientific evidence indicates that the entire planet is getting hotter. Are the world's hottest countries getting hotter? states have a huge variety of climates depending on their latitude and proximity to oceans, mountains, or the Great Lakes. This is especially true in large countries, such as the United States or Russia. Climates and temperatures vary greatly between countries and even within countries. Therefore, national borders tend to have no effect upon climate, weather, and temperatures. While geographical features such as lakes and mountain ranges can definitely impact weather and climate, national borders are typically determined by politics rather than geography. Do changes in climate correspond to national borders? However, because the South Pole now points toward the sun, the Southern Hemisphere gets more direct sunlight and enjoys its own spring and summer. When this happens, the Northern Hemisphere absorbs less sun and moves into fall and winter. Six months later, the Earth will have completed half its orbit and its North Pole will now point away from the sun. More sunlight is absorbed, and the Northern Hemisphere experiences summer. From roughly May-September each year, the Earth's tilted axis points the North Pole toward the sun, enabling sunlight to strike the Northern Hemisphere at a more direct angle. In fact, the Earth's tilt-not slight variations in its distance from the sun-is the reason Earth has seasons. As a result, the closer a country is to the poles, the less solar energy it absorbs and the cooler it is overall.Ī second, closely related cause of temperature variation is the tilt of the Earth's axis. In addition, approaching at an increased angle means the sunlight must penetrate a thicker layer of atmosphere, increasing the odds of the sunlight getting reflected, deflected or absorbed by atmospheric particles before it reaches the surface. However, the sunlight that strikes the poles does so at an increased angle, which spreads the sunlight over a greater area and makes it more likely to ricochet off (especially in areas already covered in snow). Because the Earth is roughly spherical, sunlight strikes the equator at a nearly perpendicular angle, which concentrates it in a smaller area and makes it more likely to be absorbed. The main reason countries near the equator experience hotter temperatures is the shape of the Earth. As one moves closer to the poles (further north in the Northern Hemisphere or south in the Southern Hemisphere), the seasonal weather variation and range of temperatures experienced over the course of a year increases, including significantly colder temperatures in the winter. Where are the Earth's hottest countries?Īs a rule, countries closer to the Earth's equator (zero degrees latitude) experience warmer temperatures year-round than countries farther north or south of the equator. But cooler winter nights in the 58-65☏ range lower the yearly average temperature down to a seemingly innocuous, but actually brutal mid-80s (☏) average. For example, daytime highs in Timbuktu, Mali average between 97☏ and 108☏ from March through mid-October-in fact, the average daily high in January, the coolest month of the year, is still 83☏. That means this number includes not just the summer highs, but both day and night temperatures not only in summer, but also in the spring, fall, and winter months. But keep in mind these are not average summertime highs, but average overall temperatures. How hot is the hottest country on Earth?Īt first glance, 28.83☌ / 83.89☏ seems surprisingly cool. A large part of Mali is covered by the Sahara Desert, and most of the country receives minimal rain, making drought a frequent concern. Located in West Africa, Mali actually shares borders with both Burkina Faso and Senegal, which follow it on the list. Mali is the hottest country in the world, with an average yearly temperature of 83.89☏ (28.83☌). Top 10 Hottest Countries in the World 1991-2020 (by average annual temperature ☌/☏) Is it the country that has the hottest average summer temperature, never mind the winter temperatures? Is it the country with the hottest average year-round temperature over the past 30 years? While all of these metrics have merit, this article will be using the last one mentioned. Is it the country that recorded the hottest temperature in modern history? That would be the United States, which hit 56.7C (134F) in Death Valley, California in 1913. For example, is it the country that recorded the single hottest temperature in the world in a given year? If so, that's Kuwait, whose city of Nuwaiseeb reached 53.2C (127.7F) on June 22, 2021. The first step in determining the hottest country in the world is to decide what qualifies a country as the hottest.
