Weather in August
Temperature
During August, Finneyville observes a subtle ascent to a moderately hot 84.9°F (29.4°C) from July's 86.2°F (30.1°C) in the average high-temperature. August nights experience a consistent temperature drop to a refreshing 66.2°F (19°C).Heat index
Throughout August, the heat index is evaluated at a very hot 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. 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. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
