Weather in August

August, the last month of the summer in Dean, is another hot month, with an average temperature fluctuating between 93.7°F (34.3°C) and 72.7°F (22.6°C).

Temperature

July and August are identified as the warmest months, with an average high-temperature of 93.7°F (34.3°C).

Heat index

Throughout August, the heat index is calculated to be a blazing hot 118.4°F (48°C). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
