Weather in September
Temperature
As September unfolds, the average high-temperature reaches a still hot 88.3°F (31.3°C), hinting at a slight fluctuation from the previous month. Hestle, in September, observes a steady average low-temperature of 67.5°F (19.7°C).Heat index
In September, the average heat index is evaluated at a very hot 102.2°F (39°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
