Weather in August
Temperature
A minor adjustment in Dayton's average high-temperature is noted with the start of August, touching a still hot 86.5°F (30.3°C) from July's 87.4°F (30.8°C). Dayton documents a marked decrease from day to night, with an average low of 64.6°F (18.1°C) throughout August.Heat index
During August, the heat index is appraised at a sweltering 98.6°F (37°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
