Weather in August
Temperature
As July transitions into August, the average high-temperature rests at a still hot 91.4°F (33°C), maintaining a close resemblance to the previous month. August witnesses an average nighttime temperature of 72.1°F (22.3°C).Heat index
August's mean heat index is calculated to be a life-threatening hot 114.8°F (46°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Note that heat index values are valued for light wind and location in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

July and August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: The maximum daily UV index of 7 in August interprets into the following recommendations:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
