The heat index for September is computed to be a hot 86°F (30°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
