Weather in September

September, the first month of the autumn in Sam Fordyce, is still a hot month, with an average temperature varying between 92.8°F (33.8°C) and 77.2°F (25.1°C).

Temperature

The commencement of September includes a gentle temperature shift, with the average high-temperature dropping a bit from a sweltering 99.1°F (37.3°C) in August to a hot 92.8°F (33.8°C). The average low-temperature of 77.2°F (25.1°C) is witnessed during September.

Heat index

Throughout September, the heat index is computed to be a scorching 109.4°F (43°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
