Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a moderately hot 82°F (27.8°C) from August's hot 89.2°F (31.8°C). Choctaw's average low-temperature for the month of September records at an enjoyable 61.9°F (16.6°C).Heat index
In September, the average heat index is evaluated at a tropical 87.8°F (31°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
