Welcoming August, Bismarck notes an average high-temperature of a still warm 82.2°F (27.9°C), nearly consistent with July's 83.7°F (28.7°C). Bismarck's average nighttime temperature descends significantly from the day's peak in August, settling at a mild 60.3°F (15.7°C).Heat index
The heat index in August is calculated to be 84.2°F (29°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely 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.
