Weather in August
Temperature
Greshamville measures an average high-temperature of a still hot 90°F (32.2°C) in August, nearly consistent with the preceding month. Throughout August, Greshamville experiences a low-temperature average of 69.8°F (21°C).Heat index
For August, the heat index is computed to be an extremely hot 109.4°F (43°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
