Weather in September
Temperature
September brings a slight decrease in the average high-temperature, shifting from a hot 93.6°F (34.2°C) in August to a warm 85.8°F (29.9°C). Nightly temperatures in Acme drop to an average low of 66°F (18.9°C) in September.Heat index
For September, the heat index is computed to be a tropical 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
