Heat index

September's average heat index is computed to be a torrid 38°C (100.4°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 extremely vital to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
