Weather in August
Temperature
The shift into August finds Wheaton at an average high-temperature of a moderately hot 84.9°F (29.4°C), closely comparable to July's conditions. Wheaton's August nights cool down to an average low-temperature of 67.6°F (19.8°C).Heat index
The heat index value during August is calculated to be a tropical 93.2°F (34°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
