August, the last month of the summer in Cullman, is also a hot month, with an average temperature ranging between max 88.3°F (31.3°C) and min 69.3°F (20.7°C).

Temperature

The advent of August presents an average high-temperature of a still hot 88.3°F (31.3°C), maintaining a close correlation with the preceding month. Cullman's August nights cool down to an average low-temperature of 69.3°F (20.7°C).

Heat index

The heat index value during August is computed to be a blisteringly hot 104°F (40°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. 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 heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
