The last month of the summer, August, is another hot month in Cardiff, Alabama, with an average temperature varying between 71.1°F (21.7°C) and 90.1°F (32.3°C).

Temperature

August's onset brings an average high-temperature of a still hot 90.1°F (32.3°C), showing a minute difference from July's 91°F (32.8°C). In Cardiff, an average temperature of 71.1°F (21.7°C) is noted during August nights.

Heat index

The heat index value during August is appraised at an extremely hot 107.6°F (42°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. 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. 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 relevant to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
