The heat index for September is appraised at a life-threatening hot 45°C (113°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Heat index determinations are made taking into account the shade and light air movements. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
