Weather in August
Temperature
Poplar observes a minor difference in average high-temperatures between July's 84.4°F (29.1°C) and August's 82.9°F (28.3°C). During August nights, Poplar witnesses a consistent average temperature of 63.1°F (17.3°C).Heat index
August's average heat index is calculated to be 82.4°F (28°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
