Weather in August
Temperature
The start of August marks an average high-temperature of a warm 84.9°F (29.4°C), hardly distinguishable from the conditions in July. In August, Edwardsville experiences a temperature dip to an average of 66.4°F (19.1°C) at night.Heat index
The average heat index in August is estimated at a fiery hot 95°F (35°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
