The average heat index in September is computed to be a hot 87.8°F (31°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 are particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
