Weather in August
Temperature
With the advent of August, Sumner experiences an average high-temperature of a still hot 92.8°F (33.8°C), mirroring a close resemblance to the previous month. Throughout August, an average low-temperature of 71.2°F (21.8°C) is expected in Sumner.Heat index
The heat index for August is computed to be a scorching 107.6°F (42°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.One should consider that heat index numbers are for shaded settings and light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
