Weather in August
Temperature
Norman marks the start of August with an average high-temperature of a still hot 90.1°F (32.3°C), hinting at a slight fluctuation from July's 91°F (32.8°C). August brings Norman a consistent average low-temperature of 69.3°F (20.7°C).Heat index
August's heat index is computed to be a blisteringly hot 107.6°F (42°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.Realize that the values for the heat index are set for shaded places and light winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

The average daily maximum UV index in August is 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for ordinary individuals.Note: The maximum UV index, 6 during August, leads to the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
