Weather in August
Temperature
Waterloo's shift into August is marked by a subtle change to a still hot 89.2°F (31.8°C) from July's 89.8°F (32.1°C) in temperature. Throughout August, the temperature tends to fall to a consistent average low of 69.1°F (20.6°C).Heat index
August's heat index is computed to be a blistering 105.8°F (41°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Heat index determinations are made taking into account the shade and light air movements. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. 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. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
