Temperature

August is the warmest month, with the temperature often reaching an average high of 95.9°F (35.5°C) and an average low of 75.7°F (24.3°C).

Heat index

August's heat index is estimated at an extremely hot 111.2°F (44°C). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
