Heat index

The average heat index in September is evaluated at a fiery hot 36°C (96.8°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
