During September, the heat index is calculated to be a hot 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
