Weather in September
Temperature
The arrival of September suggests a slight decrease in the average high-temperature, moving from a tropical 90.5°F (32.5°C) in August to a moderately hot 83.3°F (28.5°C). In September, the average low-temperature is a comfortable 64°F (17.8°C).Heat index
In September, the average heat index is calculated to be a hot 89.6°F (32°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
