Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a hot 91°F (32.8°C) in August to a warm 83.5°F (28.6°C). During September, the nighttime temperature averages of 64.2°F (17.9°C).Heat index
September's heat index is appraised at a hot 89.6°F (32°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
