Weather in August
Temperature
The unfolding of August shows an average high-temperature of a still hot 87.8°F (31°C), indicating a slight variance from July's 88.9°F (31.6°C). Despite higher daytime temperatures, nighttime averages fall to a comfortable 66.2°F (19°C) in August.Heat index
The heat index value for August is evaluated at a very hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Prevent overexposure. Protection from the sun's harmful effects is needed. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
