Climate is the general weather conditions in an area over a long period. The climate of an area is determined by the altitude, latitude, location of a place, and wind currents from the water bodies near the area. Climate can be classified into dry, tropical, polar, mild mid-latitude and cold mid-latitude. The countries with tropical climates are found to be the hottest.

The Hottest Capital Cities in the World

Khartoum, Sudan - 29.9 Degrees Celsius 

The climate in Khartoum is very hot, an understandable fact considering the city is located in a semi-desert climate. Rain in the city is sparse and mostly only falls between July and September. The hottest months in Khartoum are April, May, and June, where average temperates are over 40 degrees. Not only is the Sudanese capital one of the hottest capital cities in the world, but it is also one of the hottest major cities anywhere. 

Djibouti City, Djibouti - 29.8 Degrees Celsius 

Djibouti, or Djibouti City, is a capital named for the country that it is found it. With around half a million inhabitants, the population of the city represents over half of Djibouti's population as a whole. Residents of this city experience a very hot climate, with an average yearly temperature of 29.8 degrees Celsius. The city sees just over 150 ml of precipitation in an entire year. Almost every single day throughout the year experiences sunshine. 

Niamey, Niger – 29 Degrees Celsius 

Niamey, the capital city of Niger, has an average yearly temperature of 29 degrees Celsius. The city has a population of just under one million people and a very hot climate. Most of the rain that falls in Niamey occurs in scattered thundershowers in the spring. Outside of these incidences, the city stays true to its semi-arid climate and receives virtually no rainfall. 

Bangkok, Thailand - 28.6 Degrees Celsius

The capital, as well as largest city, of Thailand also happens to be one of the world's warmest. Unlike other cities on this list, which are for the most part located in desert climates, Bangkok experiences a tropical savanna climate. Even in the city's coolest month, December, temperatures rarely dip below 20 degrees. The rainy season occurs in the summertime and lasts until fall. The majority of the days in Bangkok have temperatures that are well above 30 degrees. 

Climate in the Future

Most cities experience hot temperatures now and may get even hotter in years to come due to global warming. Some expected effects of the climate change will be higher land temperatures, the growth of deserts and increase in sea levels due to the melting of the ice and glaciers in the Arctic and extreme weather may also be expected. According to the instrumental temperature record, the world temperatures on land and in the sea have increased by 33.53 °F from 1880 to 2012.
