Weather in August
Temperature
The transition into August is marked with an average high-temperature of a still tropical 92.3°F (33.5°C), showing an insignificant shift from July's 93.4°F (34.1°C). Rock Island's average nighttime temperatures present a clear contrast to its daytime highs, measured at a pleasant 69.4°F (20.8°C) in August.Heat index
August's mean heat index is calculated to be a life-threatening hot 113°F (45°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 particularly meaningful for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
