Weather in August
Temperature
Chacahoula records a slight change with August's average high-temperatures adjusting to a still hot 89.2°F (31.8°C) from July's 90°F (32.2°C). Chacahoula encounters a steady low-temperature average of 75.7°F (24.3°C) throughout the month of August.Heat index
During August, the heat index is estimated at an extremely hot 109.4°F (43°C). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.Consider that heat index readings are for situations in the shade and light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
