Weather in September
Temperature
The introduction of September sees an average high-temperature of a warm 85.3°F (29.6°C), hardly deviating from August. McTier's nighttime temperature during September is consistently averaged at an agreeable 69.1°F (20.6°C).Heat index
September's mean heat index is appraised at a torrid 96.8°F (36°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
