11 Cities with the Highest Average Temperature in the World

1. Mecca (Saudi Arabia)

Average annual temperature (Weatherbase and WWIS): 31.22 °C – 88.2 °F

Birthplace of Muhammad and holiest city of Islam aren’t the only monikers Mecca can boast with. It can also boast with being world’s hottest city in terms of average annual temperature. Thanks to the extremely arid desert climate, Mecca’s summers are absolutely scorching. Unlike other Saudi Arabian cities, Mecca manages to retain its extremely high temperatures during winter as well, and this is what helps it earn the first spot. You can choose pretty much any summer month as hottest, but let’s take June and July for example. That’s when average temperatures get stuck at 36.1 °C or 96.96 °F. Daily maximums easily reach close to 45 °C (110 °F) and it’s no wonder why Mecca is so hot. Finally, even January with average temperature of 24.65 °C – 76.37 °F isn’t cold at all.

It has been extremely hard to compile this list of 11 cities with the highest average temperature in the world due to the lack of information. Finding data doesn’t always necessarily have to be hard, but comparing it with other reputable sources, thus checking its credibility usually is. We are aware that cities like Rajahmudry (India), Warangal (India), Aden (Yemen), Omdurman (Sudan) and Nelore (India) might exhibit higher averages than some of the cities from our list, but it has been impossible to check their data through satisfactory number of sources. Furthermore, Kuwait City (Kuwait) and Nagpur (India) might showcase even higher extreme highs than cities from our list, but their averages aren’t higher due to harsher winters. Finally, 250,000 citizens is the minimum population prerequisite for our list and smaller cities couldn’t have found their spot here.
