In September, the average heat index is estimated at a hot 31°C (87.8°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often do not understand the need to rest and hydrate.
