Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from a hot 92.1°F (33.4°C) in August to a moderately hot 84.4°F (29.1°C). Throughout September, Yeager encounters an average temperature drop to a refreshing 64.6°F (18.1°C).Heat index
September's average heat index is estimated at a hot 91.4°F (33°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
