Weather in September
Temperature
The onset of September brings an average high-temperature of a still tropical 88°F (31.1°C), nearly matching the August temperature. Antelope observes a substantial disparity between daytime high and the average low-temperature of 59°F (15°C) during September nights.Heat index
September's mean heat index is estimated at a hot 87.8°F (31°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
