Weather in September

With the arrival of September, the sweltering summer conditions start to fade, giving way to the fall season. The transition from August brings a drop in temperature and longer evenings due to the shorter daylight hours. Of note in September, the rainfall upticks to 2.32" (59mm), showing a statistical increase from the previous month of August. September also heralds a minor increment in wind speed, indicating autumn's approach. The steadily decreasing UV index indicates the receding intensity of the sun.

Temperature

September comes with a drop in the average high-temperature, falling from August's fiery hot 97.3°F (36.3°C) to a tropical 87.6°F (30.9°C). Wichita Falls records an average nighttime low-temperature of 68.5°F (20.3°C) throughout September.

Heat index

For most parts of September, the heat index is estimated at a sweltering 95°F (35°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Take to heart! Snow reflection can almost magnify the Sun's UV radiation twofold.
