The average high temperature drops to a more comfortable 86.7°F (30.4°C), ensuring a noticeable difference from the peak summer months. As the fall season unravels, the daylight hours start to diminish, giving way to lengthier nights. The reduction in sunlight comes with a pleasant coolness, taking away the sting of the summer heat.

Be informed that the heat index values are oriented around shady conditions and gentle breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
