Weather in August
Temperature
The introduction of August notes a subtle temperature variation to a still hot 89.8°F (32.1°C) from July's 90.9°F (32.7°C). August nights present a sharp contrast to daytime highs, with average temperatures of 66.7°F (19.3°C).Heat index
The average heat index in August is calculated to be a blisteringly hot 107.6°F (42°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. 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 'real feel', melds the effects of warmth and moisture to generate a feeling of 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 essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

May through August, with an average maximum UV index of 6, 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 rays for the ordinary person.Note: The UV index of 6 during August leads to these advisories:
Fend off overexposure. Sun protection is vital. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
