Weather in August
Temperature
In August, Grand Coteau notes an average high-temperature of a still hot 90.1°F (32.3°C), hardly different from the preceding month. In the month of August, the nighttime temperature dips to a steady average of 73.8°F (23.2°C).Heat index
The heat index value for August is computed to be a life-threatening hot 113°F (45°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.When assessing, remember that heat index measurements are for light winds and shaded spots. 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 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
