Heat index

For most parts of September, the heat index is evaluated at an extremely hot 44°C (111.2°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.

Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
