Weather in September

The first month of the autumn, September, is still a tropical month in Ferris, Texas, with an average temperature ranging between max 87.8°F (31°C) and min 69.8°F (21°C).

Temperature

The start of September involves a subtle temperature drop, shifting from a torrid 95.5°F (35.3°C) in August to a tropical 87.8°F (31°C). During September, Ferris records an average temperature of 69.8°F (21°C) at night.

Heat index

September's heat index is calculated to be a torrid 96.8°F (36°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
