Weather in August

The beginning of August records an average high-temperature of a still hot 90.1°F (32.3°C), almost echoing the conditions of the previous month. August's nights in Grimes, Alabama, observe an average temperature of 73.6°F (23.1°C).Heat index
For most parts of August, the heat index is estimated at a blistering 109.4°F (43°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Heat index determinations are made taking into account the shade and light air movements. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 especially vital to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
