Heat index

For most parts of September, the heat index is estimated at a torrid 39°C (102.2°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
Note that heat index values are valued for light wind and location in the shade. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
