Weather in August
Temperature
Greenfield's weather in August, with an average high-temperature of a still tropical 87.1°F (30.6°C), subtly shifts from July's 88.7°F (31.5°C). During August, Greenfield experiences a consistent low-temperature average of 66.7°F (19.3°C).Heat index
August's mean heat index is estimated at a torrid 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Always consider that heat index estimations are for light winds and places in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
