Weather in August
At the dog days of summer, August sustains similar high temperatures as witnessed in July within Alexandria, Louisiana. The consistent weather pattern from the previous two months persists, characterising high temperatures and humid conditions. As the month advances, daylight hours gradually decrease, signalling the upcoming swing towards fall. August overtakes preceding months with its high amounts of rainfall, making it the wettest month of the year. Easing into September initiates a marked drop in temperature, ushering in the autumn season and a relief from the long, hot summer.Temperature
August's onset sees an average high-temperature of a still hot 92.8°F (33.8°C), exhibiting a slight fluctuation from the previous month. Throughout the month of August, Alexandria reports a steady low-temperature average of 73°F (22.8°C).Heat index
August's heat index is estimated at a life-threatening hot 120.2°F (49°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 of high significance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
