Weather in September
Temperature
As September unfolds, the average high-temperature reaches a warm 83.1°F (28.4°C), hinting at a slight fluctuation from the previous month. Trinity records an average low-temperature of 63.9°F (17.7°C) throughout the month of September.Heat index
September's mean heat index is evaluated at a hot 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Note that heat index values are valued for light wind and location in the shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.

Exercise caution. The susceptibility of light skin individuals to burns is less than 30 minutes. The most potent solar radiation is around mid-day, so one should minimize exposure to direct sunlight during this period. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
