Weather in September
Temperature
September reports an average high-temperature of a still hot 87.6°F (30.9°C), slightly varied from August's 91.6°F (33.1°C). Ethel's average low-temperature in September is measured at an agreeable 68.9°F (20.5°C).Heat index
The average heat index in September is appraised at a blistering 104°F (40°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
