Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a tropical 87.6°F (30.9°C) in August to a warm 81.1°F (27.3°C). Pfafftown's average low-temperature is measured at a refreshing 61.3°F (16.3°C) during September.Heat index
For September, the heat index is calculated to be a hot 86°F (30°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
