Weather in August
Temperature
The warmest month is August, with an average high-temperature of 91.9°F (33.3°C) and an average low-temperature of 71.1°F (21.7°C).Heat index
In August, the heat index is appraised at a blisteringly hot 109.4°F (43°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.Heat index data is primarily for areas with shade and subjected to light winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
