Weather in August

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

Temperature

As August takes hold, the average high-temperature is a still tropical 91.2°F (32.9°C), nearly mirroring that of the previous month. The average low-temperature, in August, is an agreeable 73°F (22.8°C).

Heat index

During August, the heat index is computed to be a life-threatening hot 113°F (45°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

In Start, the average relative humidity in August is 74%.

In Start, during August, the rain falls for 15.2 days and regularly aggregates up to 2.48" (63mm) of precipitation. Throughout the year, there are 156.1 rainfall days, and 36.1" (917mm) of precipitation is accumulated.

UV index

The months with the highest UV index are June through August, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for average individuals.
Note: The average daily UV index of 7 in August transforms into the following instructions:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
