Weather in August
Temperature
The initiation of August sees an average high-temperature of a still tropical 89.2°F (31.8°C), showing minor variations from the previous month. Nighttime temperatures in Vermillion consistently average a pleasant 68.5°F (20.3°C) during August.Heat index
For most parts of August, the heat index is evaluated at a blisteringly hot 105.8°F (41°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
