Weather in August
Temperature
August's advent presents an average high-temperature of a still hot 88.3°F (31.3°C), indicating a slight variation from the conditions of the previous month. In August, Hartselle's temperature tends to fall to an average low of 69.4°F (20.8°C) during the night.Heat index
For most parts of August, the heat index is computed to be a blistering 104°F (40°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
