Heat index

The heat index value for September is calculated to be a very hot 37°C (98.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
