Temperature

Aurora's weather in August, with an average high-temperature of a still warm 83.3°F (28.5°C), subtly shifts from July's 84°F (28.9°C). Aurora's temperature tends to fall to an average low of 63.9°F (17.7°C) during the nights of August.

Heat index

The average heat index in August is calculated to be a tropical 91.4°F (33°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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', is a single figure representing how weather conditions feel when combining temperature and humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
