Fire hazards, particularly in tented areas, have historically led to numerous casualties, highlighting the need for stringent safety measures.
Role of Saudi Authorities
Healthcare Policies
Saudi Arabia has implemented stringent healthcare policies to ensure the safety and well-being of Hajj pilgrims. The Ministry of Health (MOH) has established several health requirements that must be met by visitors to obtain an Entry Visa for Hajj and Umrah. These include mandatory vaccinations against diseases like Yellow Fever, Meningococcal Meningitis, and Poliomyelitis. Additionally, the MOH recommends that international pilgrims be vaccinated against seasonal influenza, particularly those at increased risk of severe influenza diseases. Health authorities in countries of origin are also required to provide information to pilgrims on infectious diseases symptoms, methods of transmission, complications, and means of prevention.
In response to international outbreaks, the MOH undertakes additional preventive precautions, following consultation with the World Health Organization (WHO). These measures are designed to prevent the spread of infection during the pilgrimage or upon return to their country of origin. The MOH Portal offers mobile apps to facilitate communication between the Ministry and beneficiaries of its services, enhancing access to healthcare resources and support.
Emergency Preparedness
The General Directorate of Civil Defence (GDCD) plays a critical role in emergency preparedness during the Hajj. The GDCD has developed a comprehensive Hajj emergency plan, which includes preventive safety measures and emergency response protocols.

Heat related effects
The environmental conditions during the Hajj in Makkah are characterized by extreme heat, with temperatures often soaring between 45 to 48 degrees Celsius during peak hours. This intense heat poses significant health risks to pilgrims, particularly increasing the incidence of heat-related illnesses such as heat exhaustion and heat stroke. The high humidity, which can reach up to 60%, further exacerbates these conditions, making it difficult for the body to effectively dissipate heat through perspiration.
The physical exertion associated with performing Hajj rituals, combined with the crowded conditions, increases the vulnerability of pilgrims to these heat-related effects. Vulnerable groups, including the elderly, young children, and those with pre-existing health conditions, are at an even greater risk. The symptoms of heat-related illnesses can range from mild, such as dizziness and dehydration, to severe conditions that can be life-threatening.
Weather data analysis
Recent studies indicate a troubling trend in the rising temperatures in Makkah, with both dry and wet bulb temperatures showing significant increases over recent decades. This trend is strongly correlated with an uptick in cases of heat-related illnesses among Hajj pilgrims. Projections suggest that, without significant intervention, heat stress during Hajj could frequently exceed extreme danger thresholds within the coming decades.
In response to these challenges, the National Center of Meteorology (NCM) has implemented several measures to better inform and protect pilgrims. The establishment of a media and awareness center in Mina is a pivotal step, offering round-the-clock weather updates and health advisories in multiple languages. This center not only aims to enhance the safety and comfort of pilgrims through timely weather information but also provides specific services for pilgrims with disabilities, ensuring inclusive access to necessary information.
Furthermore, regional centers affiliated with the NCM, such as the Regional Center for Climate Change and the Sand and Dust Storm Warning Regional Center, are actively conducting research to better understand and mitigate the impacts of adverse weather conditions. These centers play a crucial role in developing strategies for weather improvement, including cloud seeding programs, which could potentially alleviate some of the harsh weather conditions experienced during the Hajj.
