Weather in August
Temperature
The warmest time of the year is August, with temperatures averaging a high of 92.8°F (33.8°C) and a low of 78.4°F (25.8°C).Heat index
The heat index value for August is estimated at a life-threatening hot 116.6°F (47°C). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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 increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Deflect overexposure. Sun protection is a necessity. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Enhance your sun protection with tightly woven, yet airy clothing.
