Weather in September
Temperature
Niles experiences an average high-temperature of a warm 85.6°F (29.8°C) in September, subtly different from August's 89.6°F (32°C). Niles observes an average nighttime temperature of 66.9°F (19.4°C) during September.Heat index
Throughout September, the heat index is calculated to be a fiery hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
