Heat index

For September, the heat index is estimated at a scorching 44°C (111.2°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
