Weather in August
Temperature
In Roy, August records the highest average temperatures, peaking at 91.9°F (33.3°C) and reaching a low of 75.4°F (24.1°C).Heat index
The heat index value during August is estimated at a life-threatening hot 118.4°F (48°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.Note that heat index values are valued for light wind and location in the shade. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. 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 especially crucial for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
