Weather in August
Temperature
Bismarck in August witnesses an average high-temperature of a still tropical 91°F (32.8°C), indicating a slight variation from July's 91.9°F (33.3°C). August witnesses an average low-temperature hovering around a pleasant 70°F (21.1°C).Heat index
Throughout August, the heat index is appraised at a blisteringly hot 111.2°F (44°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.Observations indicate that the heat index values are for shady locations with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Resist overexposure. Safeguarding from solar damage is indispensable. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
