Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still tropical 86°F (30°C), closely aligned with August's 87.6°F (30.9°C). North El Monte encounters a substantial decline from its daily high to a low-temperature of 63.5°F (17.5°C) during September nights.Heat index
For most parts of September, the heat index is computed to be a tropical 87.8°F (31°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.Realize that the values for the heat index are set for shaded places and light winds. 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 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
