Hajj Peak 2026: Temperatures Predicted to Reach 47 Degrees Celsius

Extreme heat is forecast for Mecca, Saudi Arabia, during the 2026 Hajj pilgrimage, with temperatures predicted to reach 47 degrees Celsius.

The Saudi Ministry of Health has issued a strong advisory to Hajj pilgrims, urging them to consistently use umbrellas. This measure is intended to prevent heat exhaustion, sunstroke, and dehydration as they navigate between holy sites. The ministry highlighted that using an umbrella can lower the ambient temperature by as much as 10 degrees Celsius, thereby reducing the physical strain during the demanding rituals.

These warnings come as the Saudi Meteorological Center anticipates scorching weather along the pilgrims' routes. Temperatures in Mecca are expected to hit 47 degrees Celsius, while Madinah could see highs of 44 degrees Celsius. High humidity, up to 40 percent, and dusty winds in open areas are also concerns that could exacerbate health issues for the estimated 1.6 million pilgrims expected to gather.

Indonesian authorities are also preparing pilgrims for the conditions. The Ministry of Religious Affairs (Kemenhaj) Indonesia is reminding them to maintain physical health, get adequate rest, eat regularly, and drink plenty of water. They are also advised to pack only necessary items, such as identification documents, prayer essentials, comfortable footwear, and personal hygiene kits, while avoiding large suitcases, heavy items, excessive jewelry, or large amounts of cash.

Indonesian pilgrims are scheduled to begin their movement from hotels to Arafah on Monday, May 25th, corresponding to the 8th of Dhu al-Hijjah. This relocation will occur in three phases throughout the day.
