Weather in August
Temperature
The arrival of August sees a recorded average high-temperature of a still moderately hot 84.4°F (29.1°C), showing little divergence from the previous month's conditions. August nights in Omaha, Illinois, are marked by an average temperature drop to an enjoyable 65.8°F (18.8°C).Heat index
Throughout August, the heat index is computed to be a torrid 95°F (35°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
