JEDDAH: Temperatures during Hajj season this year are expected to reach 50 degrees Celsius on some days, Saudi officials said Sunday.  Saudi Arabia’s General Authority of Meteorology and Environmental protection also expects humidity to reach 85 percent, making the climate feel even hotter.   The authority said there was a chance of some rain clouds over Makkah, where pilgrims arrive to circle the Kaaba, and visit nearby holy sites that are visited during the pilgrimage.  It also expects wind that could lift dust and a chance of rainfall, especially in the afternoon and evening hours, over Makkah. In 2018, pilgrims were met with heavy rain on the first evening of Hajj.
