September's heat index is computed to be a hot 30°C (86°F). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 hold great significance to 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.
