Arlington Heights's weather in August indicates an average high-temperature of a still warm 80.8°F (27.1°C), nearly consistent with the 82°F (27.8°C) of July. Throughout August, Arlington Heights anticipates an average low-temperature of 63.3°F (17.4°C).Heat index
The heat index value during August is evaluated at 84.2°F (29°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
