Weather in August
Temperature
The unfolding of August shows an average high-temperature of a still hot 90.3°F (32.4°C), indicating a slight variance from July's 90.9°F (32.7°C). In Winona, the average nighttime temperature during August is an agreeable 71.2°F (21.8°C).Heat index
The average heat index in August is computed to be a blisteringly hot 109.4°F (43°C). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
