In September, the average heat index is estimated at a hot 87.8°F (31°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
