Weather in September
Temperature
With the arrival of September, Glencoe notices a mild change in the average high-temperature, sliding from August's tropical 88.7°F (31.5°C) to a warm 82.2°F (27.9°C). Throughout September, Glencoe witnesses a nighttime temperature average of 61.7°F (16.5°C).Heat index
September's heat index is computed to be a tropical 87.8°F (31°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
