Weather in August
Temperature
With August's arrival, Jefferson's weather records an average high-temperature of a still tropical 92.1°F (33.4°C), marking little difference from July's 92.8°F (33.8°C). The average low-temperature, in August, is a pleasant 72.3°F (22.4°C).Heat index
The heat index for August is estimated at a blazing hot 114.8°F (46°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
