What is mecca rainfall?

As an AI language model, I do not have access to real-time weather data. However, Mecca is located in a desert region, called the Hejaz region, in Saudi Arabia. This region is known for its hot and dry climate, with very little rainfall throughout the year. On average, Mecca experiences less than 100mm of rainfall per year, with most of it occurring during the months of November to February. Due to its arid climate, water is a scarce resource in Mecca, and the city relies heavily on desalination plants to meet its water needs.
