Weather in September
Temperature
As September arrives, Terlingua's weather displays a minor decrease in high-temperatures, transitioning from August's 93.6°F (34.2°C) to a still tropical 87.1°F (30.6°C). The low-temperature averages to a pleasant 70.2°F (21.2°C) during the nights of September.Heat index
In September, the heat index is appraised at a tropical 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
