Weather in September
Temperature
September's weather displays an average high-temperature of a warm 84.7°F (29.3°C), slightly varied from August's 89.2°F (31.8°C). September witnesses an average nighttime temperature of 67.8°F (19.9°C).Heat index
For most parts of September, the heat index is calculated to be a tropical 93.2°F (34°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
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. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
