September's heat index is calculated to be a hot 31°C (87.8°F). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Heat index determinations are made taking into account the shade and light air movements. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
