Weather in September
Temperature
As September begins, there is a minor decrease in the average high-temperature, softly falling from a tropical 89.2°F (31.8°C) in August to a moderately hot 83.5°F (28.6°C). An average low-temperature of 63.7°F (17.6°C) is observed during September nights in Due West.Heat index
The heat index in September is computed to be a hot 89.6°F (32°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Understanding the heat index involves considering values for shaded locales with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. 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 particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
