Weather in September
Temperature
September's arrival signals a moderate reduction in the average high-temperature, easing from a hot 86.9°F (30.5°C) in August to a warm 81.5°F (27.5°C). Nighttime temperature lowers to an average of 62.4°F (16.9°C) in September.Heat index
September's mean heat index is computed to be a tropical 86°F (30°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
