Weather in August
Temperature
Shifting into August, Columbus records an average high-temperature of a still hot 93°F (33.9°C), presenting minor fluctuations compared to the previous month. Despite drastic daytime highs, Columbus logs an average low-temperature reading of 71.1°F (21.7°C) throughout August.Heat index
In August, the heat index is appraised at a life-threatening hot 114.8°F (46°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.Know that the heat index computations account for shaded terrains and slight winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
