Weather in September
Temperature
As August transitions into September, Antioch sees a gentle drop in the average high-temperature, transitioning from a tropical 93.7°F (34.3°C) to a still hot 88°F (31.1°C). Antioch in September experiences a low-temperature average of 66.9°F (19.4°C).Heat index
For September, the heat index is evaluated at a torrid 100.4°F (38°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
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. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. 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 faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
