Weather in August
Temperature
The arrival of August brings an average high-temperature of a still hot 90.1°F (32.3°C), subtly diverging from July's 90.3°F (32.4°C). An average minimum temperature of 74.8°F (23.8°C) marks the month of August.Heat index
For August, the heat index is appraised at a life-threatening hot 113°F (45°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Be advised, the heat index considers values for conditions in shade and with a light breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
