Weather in August
Temperature
A minor adjustment in Council Bluffs's average high-temperature is noted with the start of August, touching a still warm 82.6°F (28.1°C) from July's 84.4°F (29.1°C). Council Bluffs experiences a mean temperature of 63.1°F (17.3°C) during August nights.Heat index
Throughout August, the heat index is computed to be a hot 89.6°F (32°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
