For most parts of September, the heat index is computed to be a hot 86°F (30°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for 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.
