Weather in September
Temperature
September's onset brings an average high-temperature of a still hot 86.7°F (30.4°C), showing a minute difference from August's 90°F (32.2°C). Throughout September, an average nighttime temperature of 71.2°F (21.8°C) is experienced in Lake Arthur.Heat index
September's average heat index is computed to be a sweltering 100.4°F (38°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
