Weather in September
Temperature
September's average high-temperature stands at a still hot 87.4°F (30.8°C), showing little deviation from August's 90.5°F (32.5°C). Throughout September, Alpine Heights witnesses a consistent average low-temperature of 71.2°F (21.8°C).Heat index
The average heat index in September is evaluated at a very hot 100.4°F (38°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
