Weather in August
Temperature
The arrival of August is marked by an average high-temperature of a still tropical 90.3°F (32.4°C), bearing a close resemblance to July. Marianna experiences a mean low-temperature of 74.5°F (23.6°C) during August.Heat index
Throughout August, the heat index is evaluated at a life-threatening hot 113°F (45°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
