Weather in August
Temperature
Greenfield's transition from July to August introduces an average high-temperature of a still hot 93.2°F (34°C), marking an insignificant variation from the 94.6°F (34.8°C). The average low-temperature, in August, is an agreeable 72.7°F (22.6°C).Heat index
Throughout August, the heat index is estimated at a blisteringly hot 104°F (40°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
