Weather in August
Temperature
With the start of August, Grace measures an average high-temperature of a still hot 90.7°F (32.6°C), not significantly differing from July's 91.8°F (33.2°C). During the month of August, an average low-temperature of 72.1°F (22.3°C) is recorded.Heat index
In August, the average heat index is evaluated at a blazing hot 113°F (45°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.When assessing, remember that heat index measurements are for light winds and shaded spots. 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', evaluates the perceived heat by adding the effect of moisture in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Sunshine

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for ordinary individuals.Note: A maximum daily UV index of 7 during August morphs into the following directions:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
