Heat index

For October, the heat index is evaluated at a burning hot 47°C (116.6°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
