September weather forecast
Thomasville, GA

September in Thomasville begins to see a slight cooling trend, ushering in the early signs of fall. Thomasville experiences reduced daylight hours, lower temperatures, and a decline in rainfall, standing at 1.57" (40mm), from the peak summer season. Nevertheless, September is still considerably warm compared to the approaching months. In terms of wind speeds, September brings slightly stronger winds than August. This change in wind patterns effectively disperses humidity, offering a much-needed respite toward the end of the month.

Temperature

The commencement of September records an average high-temperature of a still tropical 86.9°F (30.5°C), barely varying from August's 90.3°F (32.4°C). Throughout September, the nighttime temperature averages to an agreeable 69.3°F (20.7°C).

Heat index

The heat index for September is evaluated at a very hot 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
