Weather in August

As the final month of summer, August sheds a bit of the intense heat experienced in Lake Charles, Louisiana. August recaptures July's heat, boasting the second-highest recorded temperature of 91.4°F (33°C) for the year. The increase in cloud cover provides a much-welcomed cooling effect against the high temperatures. Despite the mild reduction in heat, the weather stays on the warmer side. As the simmering heat of August starts to wane, the city braces itself for the arrival of autumn in September.

Temperature

August, with average temperatures reaching a high of 91.4°F (33°C) and a low of 75.6°F (24.2°C), is the warmest month in Lake Charles.

Heat index

The average heat index in August is calculated to be a blazing hot 116.6°F (47°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Heat index determinations are made taking into account the shade and light air movements. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
