Weather in August

Slight changes mark weather transitioning from July to August. Rainfall in August slightly increases to 4.61" (117mm), the highest for the year. The daylight hours decrease further while the weather remains hot, hinting at the forthcoming retreat of summer. August in Melville, Louisiana makes its mark with sultry temperatures and high humidity alongside frequently brilliant sunshine. The persistent summer winds serve as a slight relief from the oppressive heat.

Temperature

Entering August, Melville's average high-temperature reads a still tropical 90.9°F (32.7°C), indicating a close resemblance to the previous month's climate. An average low-temperature of 73.4°F (23°C) is common during the nights of August.

Heat index

Throughout August, the heat index is appraised at a burning hot 116.6°F (47°C). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
