Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a tropical 92.8°F (33.8°C) to a warm 84.2°F (29°C). An average low-temperature of 65.3°F (18.5°C) is recorded in the month of September.Heat index
For September, the heat index is evaluated at a tropical 87.8°F (31°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
