Weather in August

August brings no reprieve in temperatures for Madison, Alabama as summer persists. August and July compete fiercely for the title of the hottest month, with temperatures matching closely.

August gives final expression to the sultry summer before preparing to welcome the fall season.

For clarity, heat index numbers account for light winds and areas under shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
