Weather in August
Temperature
With the onset of August, a modest change to a still hot 89.1°F (31.7°C) from July's 89.6°F (32°C) is noted in high-temperature. Throughout the month of August, Destrehan witnesses an average temperature of 77.5°F (25.3°C).Heat index
The heat index value during August is evaluated at an extremely hot 107.6°F (42°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
