The heat index in September is calculated to be a hot 87.8°F (31°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children.
