Weather in August

The last month of the summer, August, is another tropical month in Monterey, Louisiana, with an average temperature varying between 73°F (22.8°C) and 91.2°F (32.9°C).

Temperature

The transition from July to August sees average high-temperatures adjusting to a still tropical 91.2°F (32.9°C), from a not significantly different 91.8°F (33.2°C). Throughout August, an average nighttime temperature of 73°F (22.8°C) is experienced in Monterey.

Heat index

The heat index for August is evaluated at a blazing hot 114.8°F (46°C). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Heat index details are generally centered around shaded locations and a mild breeze. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
