About Riyadh
Riyadh is the capital and largest city of Saudi Arabia. It is also the capital of the Riyadh Province and the centre of the Riyadh Governorate. Located on the eastern bank of Wadi Hanifa, the current form of the metropolis largely emerged in the 1950s as an expansion of the 18th-century walled town, following the dismantling of its defensive fortifications.

How we ranked these
Each month is scored on temperature comfort (18–27°C avg high is the sweet spot), rainfall (more rain days = lower score), snow days, and peak hazard seasons (hurricanes, monsoons, etc.). Green-tier months are within ideal range with no major issues. Yellow are workable but with trade-offs. Red has at least one significant problem — extreme heat or cold, heavy rain, or peak storm season.
