Weather in August
Temperature
The commencement of August records an average high-temperature of a still hot 90.9°F (32.7°C), barely varying from July's 91°F (32.8°C). Throughout August, Theressa's nights cool down to an average of 74.8°F (23.8°C).Heat index
August's mean heat index is estimated at a burning hot 114.8°F (46°C). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 extremely vital to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

The months with the highest UV index are May through August, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: The UV index of 7 during August leads to these advisories:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
