Weather in August

The last month of the summer, August, is also a hot month in Gilliam, Louisiana, with an average temperature varying between 94.6°F (34.8°C) and 73°F (22.8°C).

Temperature

August welcomes an average high-temperature of a hot 94.6°F (34.8°C), not much different from the preceding month. The nighttime temperature, during August, averages of 73°F (22.8°C).

Heat index

The heat index value during August is estimated at a life-threatening hot 118.4°F (48°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
