Weather in August
Temperature
As Griffithsville transitions from July to August, the average high-temperatures adjust to a moderately hot 84.9°F (29.4°C), nearly the same as the previous 86.4°F (30.2°C). Griffithsville sees a consistent average low-temperature of 61.5°F (16.4°C) in August, indicating a substantial decrease from the day's temperature.Heat index
Throughout August, the heat index is calculated to be a sweltering 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
