Weather in August
Temperature
During August, Ellisville observes a subtle ascent to a still hot 90.1°F (32.3°C) from July's 90.7°F (32.6°C) in the average high-temperature. Ellisville reports a consistent average low-temperature of 75°F (23.9°C) throughout August nights.Heat index
August's average heat index is appraised at a life-threatening hot 113°F (45°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Be advised, the heat index considers values for conditions in shade and with a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: The UV index of 7 during August translates into the following guidance:
Fend off overexposure. Sun protection is vital. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
