Weather in September
Temperature
As September unfolds, the average high-temperature reaches a warm 85.3°F (29.6°C), hinting at a slight fluctuation from the previous month. Throughout the month of September, Atwell expects an average low of 67.1°F (19.5°C).Heat index
During September, the heat index is evaluated at a fiery hot 95°F (35°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
