Weather in August
Temperature
August registers as the month with the highest average temperatures, reaching 91.9°F (33.3°C) at its peak and 66.4°F (19.1°C) at the lowest.Heat index
August's heat index is computed to be a torrid 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Sunshine

The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: The UV index of 7 in August translates into these instructions:
Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
