Summer heat makes outdoor rituals demanding, winter cold affects Muzdalifah nights, and rain can disrupt tawaf but is considered a blessing.
During summer Hajj, outdoor rituals like standing at Arafat for hours, overnight at Muzdalifah, and the Mina stay become physically grueling. The stoning of Jamarat in dense crowds is particularly challenging in extreme heat. Authorities have installed misting systems but personal heat management remains essential.
Winter transforms the experience. Tawaf and sa'i become comfortable, but the overnight Muzdalifah stay can be surprisingly cold at 10 to 15 degrees. Bring warm layers and a blanket. Mina tents are unheated.
Rain is infrequent but impactful. The Mataf can become slippery, and tawaf may be suspended. Flash flooding has affected Mina historically. However, rain during Hajj, especially at Arafat, is considered a great blessing.
