Weather in September
Temperature
September brings a minor shift in the average high-temperature, adjusting from a tropical 91.8°F (33.2°C) in August to a warm 83.1°F (28.4°C). An average low-temperature of 63.1°F (17.3°C) is common during the nights of September.Heat index
September's average heat index is calculated to be 84.2°F (29°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
