Weather in September
Temperature
An average high-temperature of a still tropical 87.8°F (31°C) marks September, exhibiting a close resemblance to the conditions in August. During the nights in September, Bay Minette observes an average low-temperature of 70.2°F (21.2°C).Heat index
September's heat index is estimated at a scorching 104°F (40°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Metrics for the heat index primarily focus on shaded spots and light wind conditions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
