Weather in August
Temperature
August welcomes an average high-temperature of a warm 85.1°F (29.5°C), not much different from the preceding month. Throughout August, a steady low-temperature average of 66.7°F (19.3°C) is noted.Heat index
The heat index for August is calculated to be a torrid 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for 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, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
