Weather in August
Temperature
August's presence records an average high-temperature of a still hot 86.7°F (30.4°C), closely mirroring July's climate. Metropolis, during the month of August, experiences an average low-temperature of 67.3°F (19.6°C).Heat index
During August, the heat index is appraised at a sweltering 98.6°F (37°C). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

The months with the highest UV index in Metropolis are May through August, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the average person.Note: An average maximum UV index of 6 in August leads to these recommendations:
Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
