Weather in August
Temperature
Temperature records mark August as the warmest month, with highs averaging 90°F (32.2°C) and lows at 75.7°F (24.3°C).Heat index
In August, the heat index is estimated at a burning hot 113°F (45°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the average person.Note: In August, the maximum UV index of 7 suggests these recommendations:
Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
