Weather in August

The last month of the summer, August, is also a hot month in Mountain Grove, Alabama, with an average temperature varying between 87.4°F (30.8°C) and 68.7°F (20.4°C).

Temperature

With the onset of August, a modest change to a still hot 87.4°F (30.8°C) from July's 88.7°F (31.5°C) is noted in high-temperature. In Mountain Grove, the August nights cool down to an average low of 68.7°F (20.4°C).

Heat index

August's average heat index is calculated to be a torrid 102.2°F (39°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
