The weather during August records an average high-temperature of a still warm 81.3°F (27.4°C), closely mirroring the preceding month. Keisterville records a marked divergence from the day's high temperatures, with nights in August averaging at a refreshing 59°F (15°C).Heat index
August's average heat index is computed to be a tropical 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Know that the heat index computations account for shaded terrains and slight winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
