For September, the heat index is evaluated at a tropical 89.6°F (32°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
