Weather in August

August in Thibodaux, Louisiana marches on with the summer's high temperature trend carried over from July. August musters all signs of nearing end of summer with cooler evenings and lesser sunshine hours.

Temperature

During August, Thibodaux records an average high-temperature of a still hot 89.2°F (31.8°C), marking a slight divergence from July's 90°F (32.2°C). The average low-temperature during August nights is a moderately hot 75.7°F (24.3°C).

Heat index

August's average heat index is evaluated at an extremely hot 109.4°F (43°C). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
Know that the heat index computations account for shaded terrains and slight winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
