Weather in August
Temperature
August is the month when Iowa experiences its warmest temperatures, averaging a high of 91.4°F (33°C) and a low of 75.6°F (24.2°C).Heat index
For most parts of August, the heat index is appraised at a burning hot 116.6°F (47°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.For clarity, heat index numbers account for light winds and areas under shade. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
Humidity
The average relative humidity in August is 77%.Rainfall
The month with the most rainfall is August, when the rain falls for 22.2 days and typically aggregates up to 5.75" (146mm) of precipitation.Snowfall

Sunshine

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: The average daily UV index of 7 in August transforms into the following instructions:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
