Weather in September
Temperature
The beginning of September subtly marks a decrease in the average high-temperature, transitioning from a hot 88.3°F (31.3°C) in August to a moderately hot 82.9°F (28.3°C). The average temperature drops to a refreshing 65.5°F (18.6°C) during the night in the month of September.Heat index
During September, the heat index is computed to be a tropical 89.6°F (32°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
