San Francisco Frontiers - Hajj pilgrims gather in Mecca under scorching desert sun

Officials have beefed up heat mitigation measures hoping to avoid a repeat of last year's hajj, which saw 1,301 pilgrims die as temperatures reached 51.8 degrees Celsius (125.2 Fahrenheit).

Temperatures were forecast to exceed 40 degrees Celsius this week as one of the world's largest annual religious gatherings starts on Wednesday.

The hajj, one of the five pillars of Islam, must be performed at least once by all Muslims with the means.

As of Friday, more than 1.3 million pilgrims had arrived in Saudi Arabia for the multi-day pilgrimage, according to officials.

This year, authorities have mobilised more than 40 government agencies and 250,000 officials, doubling their efforts against heat-related illness following the lethal heatwave of 2024.

Shaded areas have been expanded by 50,000 square metres (12 acres), thousands more medics will be on standby, and more than 400 cooling units will be deployed, Saudi Arabia's hajj minister Tawfiq al-Rabiah told AFP last week.

On Monday, with temperatures topping 40 degrees Celsius, the health ministry said 44 cases of heatstroke had already been treated.

The latest artificial intelligence technology will also help monitor the flood of data and footage, including video from a new fleet of drones, from across Mecca to better manage the mammoth crowds.

Despite the punishing heat, pilgrims were overjoyed as they arrived in Mecca.

- 'Very, very, very hot' -

"This is really a blessing from Allah," Abdul Majid Ati, a Filipino lawyer and Sharia counsellor, told AFP near the Grand Mosque.

"We feel so peaceful and safe in this place."

Abdulhamid, from Nigeria, said he was "very happy" to be performing his second pilgrimage in a row at just 27 years old.

But the young man said he never walks out without his sunglasses, describing the temperatures in Mecca as "very, very, very hot".

The rites in the holy city and its surroundings, which follow a lunar calendar, fall again this year during the hot month of June.

Last year, most of the deaths were among unregistered pilgrims who lacked access to air-conditioned tents and buses.

"They were caught by surprise because the intensity of the heat was so high that their adaptation measures failed," said Fahad Saeed of Climate Analytics, a think tank based in Germany.

In the run-up to this year's hajj, Saudi authorities launched a widespread crackdown on unregistered worshippers, using frequent raids, drone surveillance and a barrage of text alerts.

- Arrest and deportation -

Hajj permits are allocated to countries on a quota system and distributed to individuals by lottery.

But even for those who can obtain them, the steep costs prompt many to attempt the hajj without a permit -- though they risk arrest and deportation if caught.

Along with hefty fines, those found illegally entering Mecca during the hajj face a potential 10-year ban from Saudi Arabia.

Large crowds at the hajj have proved hazardous in the past, most recently in 2015 when a stampede during the "stoning the devil" ritual in Mina, near Mecca, killed up to 2,300 people in the deadliest hajj disaster.

Saudi Arabia, which is home to Islam's holiest sanctuaries in Mecca and Medina, earns billions of dollars each year from the hajj and pilgrimages known as umrah, undertaken at other times of the year.

The pilgrimages are a also source of prestige for the Saudi monarch, who is known as the Custodian of the Two Holy Mosques of Mecca and Medina.

For Mariama, a 52-year-old pilgrim from Senegal, the journey to Mecca has fulfilled a life-long dream.

"I was dreaming about it, thinking about it every time to come here to do the hajj," she said.
