Weather in August
Temperature
Winona notes an average high-temperature of a still hot 90.3°F (32.4°C) in August, displaying minor variation from July. Throughout the month of August, Winona observes an average nighttime temperature of 71.2°F (21.8°C).Heat index
The heat index in August is estimated at a blistering 109.4°F (43°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
