The heat index for September is computed to be a hot 86°F (30°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
