Saudi Arabia’s National Centre of Meteorology (NCM) has issued strong heatwave warnings for Hajj 2025, urging millions of pilgrims to take precautions as daytime temperatures soar to between 40°C and 47°C.
The NCM forecasted challenging weather conditions for the annual pilgrimage, including extreme heat, potential thunderstorms, dust storms, and reduced visibility in key areas around the holy sites of Mecca and Medina.
According to the NCM, the humidity is expected to range from 15% to 60%, making the heat feel even more intense for pilgrims performing their rites under the scorching sun.
“Northerly to northwesterly winds blowing at speeds between 25 and 35 kilometres per hour may raise dust and significantly reduce visibility, especially along highways and open areas leading to the holy sites,” the NCM said.
The centre also warned of possible thunderstorms over the Taif highlands between the 8th and 13th of Dhu Al Hijjah—the Islamic month during which Hajj takes place. These storms may extend to Mecca and its surrounding areas, bringing strong downdrafts that could worsen dusty conditions.
In response to the forecast, Saudi authorities have stepped up preparations to ensure the safety and comfort of pilgrims during the pilgrimage.
Pilgrims are advised to stay well hydrated by drinking plenty of water and to protect themselves from the sun by using umbrellas, hats, and sunscreen. They are also urged to follow official weather updates closely throughout their stay.
To improve comfort, the authorities have installed 883 air conditioning units, 244 mist fans, and over 3,000 ventilation fans throughout the holy sites. Additionally, 432 fragrance diffusers have been placed to help create a calming atmosphere amid the desert heat.
A recently inaugurated cooled pedestrian walkway in Makkah forms part of the “Cooled Roads Initiative,” designed to lower surface temperatures and provide relief for the millions of pilgrims walking long distances.
Mobility assistance has also been increased with the deployment of 400 electric carts to help elderly and physically challenged pilgrims complete their rites more easily.
The Saudi Ministry of Health reported five cases of heat exhaustion among the more than one million pilgrims already present in the Kingdom. All affected individuals have received immediate medical attention and are currently in stable condition.
Health teams remain on high alert to quickly respond to similar cases, as heat exhaustion can rapidly develop into heat stroke—a serious, life-threatening condition if not treated within 10 to 15 minutes. Symptoms include headache, dizziness, excessive sweating, nausea, and severe thirst.
To further protect pilgrims, the Ministry of Health, in cooperation with the Royal Commission for Makkah City and Holy Sites, announced additional measures to combat extreme heat. These include planting more than 10,000 trees to increase shade, installing 400 extra water coolers and misting fans, and expanding shaded pedestrian pathways.
These combined efforts aim to reduce the risk of heat-related illnesses and make the pilgrimage safer and more comfortable during the hottest time of the year.
Hajj is one of the largest religious gatherings in the world, attracting millions of Muslims from across the globe every year. The extreme heat and harsh desert conditions present significant challenges, especially to the elderly, children, and those with pre-existing health conditions.
The Saudi government’s proactive steps highlight their commitment to safeguarding the health and welfare of all pilgrims during this sacred journey, despite the harsh weather.
As Hajj progresses, pilgrims are reminded to prioritize their health and follow safety guidelines issued by authorities to complete their spiritual rites safely amid the intense summer heat.
