Weather in August

The last month of the summer, August, is another hot month in Dexter, Mississippi, with an average temperature varying between 90.5°F (32.5°C) and 72.7°F (22.6°C).

Temperature

The onset of August notes an average high-temperature of a still tropical 90.5°F (32.5°C), subtly shifted from July's 91°F (32.8°C). Throughout August, the temperature falls to an average low of 72.7°F (22.6°C).

Heat index

In August, the heat index is estimated at a blazing hot 113°F (45°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
