Weather in August
Temperature
The advent of August signifies a minor shift to an average high-temperature of a still hot 91.4°F (33°C), aligning closely with July. Rolla records a marked divergence from the day's high temperatures, with nights in August averaging at an agreeable 69.1°F (20.6°C).Heat index
During August, the heat index is computed to be a sweltering 96.8°F (36°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
