Heat index

For most parts of September, the heat index is computed to be a blisteringly hot 107.6°F (42°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. To cut down UV radiation exposure by about half, sport a wide-brim hat.
