Weather in September
Temperature
As August transitions into September, Zacarter records an average high-temperature of a still hot 86.4°F (30.2°C), showing a gentle shift from the preceding month. September brings with it a nighttime average temperature of 73°F (22.8°C).Heat index
September's average heat index is computed to be a sweltering 100.4°F (38°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for 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.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
