Weather in August
Temperature
August's commencement is accompanied by an average high-temperature of a still hot 93.7°F (34.3°C), diverging marginally from July's 94.1°F (34.5°C). During August, the average low-temperature is recorded at a pleasant 72.1°F (22.3°C).Heat index
For most parts of August, the heat index is evaluated at a life-threatening hot 118.4°F (48°C). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
