Weather in September
Temperature
With the onset of September, Clarkridge's average high-temperature slightly adjusts, moderately receding from August's tropical 89.8°F (32.1°C) to a warm 82.4°F (28°C). September nights indicate a noticeable temperature drop from the daytime highs, with an average reading lowering to a moderate 60.4°F (15.8°C).Heat index
In September, the average heat index is computed to be a hot 87.8°F (31°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. 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 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
