Weather in August
Temperature
With an average high-temperature of 93.4°F (34.1°C) and an average low-temperature of 72.1°F (22.3°C), August is the warmest month.Heat index
The heat index in August is calculated to be a blisteringly hot 109.4°F (43°C). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.In the scope of the heat index, its values resonate with shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
