Weather in August
Temperature
The advent of August brings an average high-temperature of a still tropical 87.4°F (30.8°C), exhibiting minor difference from the previous month. Throughout the month of August, Guntersville witnesses an average low-temperature of 67.6°F (19.8°C).Heat index
Throughout August, the heat index is estimated at a torrid 102.2°F (39°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Deter overexposure. Protecting against the sun's effects is essential. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
