Weather in August
Temperature
With August's advent, Riverdale sees an average high-temperature of a still tropical 89.1°F (31.7°C), subtly shifted from July's 90.3°F (32.4°C). During the month of August, Riverdale experiences a steady low-temperature average of 70.3°F (21.3°C).Heat index
The heat index value for August is evaluated at a blistering 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
