But there are also places on our planet with year-long warm weather. Temperatures there, on average, tend to never drop below 20 °C / 68 °F. But which places are the absolute warmest in the world? The following shows you the Top 10 of the warmest cities in the world. The ranking features major cities with a population of at least 100,000 and is based on the average annual temperature in said city.

The 10 Warmest Cities in the World

1. Bosaso, Somalia

Bosaso is the warmest city in the world. The average daily temperature in Bosaso reaches 30 °C / 86 °F. The city is located in the autonomous region of Puntland in Northern Somalia.
