Weather in September
Temperature
With the transition into September, Palmdale notes an average high-temperature of a still hot 88.2°F (31.2°C), closely resembling August. Palmdale records a mean low-temperature of 74.5°F (23.6°C) in September.Heat index
September's mean heat index is estimated at a blistering 107.6°F (42°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
