Weather in August
Temperature
The month of August sees the highest average temperatures, reaching 92.1°F (33.4°C) at the peak and 72.1°F (22.3°C) at the low.Heat index
August's heat index is evaluated at a blazing hot 116.6°F (47°C). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', 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 swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
