Weather in September
Temperature
As September unfolds, the average high-temperature reaches a still tropical 87.8°F (31°C), hinting at a slight fluctuation from the previous month. The low-temperature average for McKinley during September stands at a comfortable 67.3°F (19.6°C).Heat index
In September, the average heat index is estimated at a fiery hot 100.4°F (38°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.For clarity, heat index numbers account for light winds and areas under shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
