Weather in August
Temperature
Hartselle signifies an average high-temperature of a still tropical 88.3°F (31.3°C) in August, closely mirroring the 89.1°F (31.7°C) of July. An average nighttime temperature of 69.4°F (20.8°C) is witnessed throughout August.Heat index
In August, the heat index is computed to be a blisteringly hot 104°F (40°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
