Weather in August

The last month of the summer, August, is another hot month in Simpson, Louisiana, with an average temperature fluctuating between 73.2°F (22.9°C) and 93.7°F (34.3°C).

Temperature

The transition into August shows a subtle variation to a still hot 93.7°F (34.3°C) from July's 93.9°F (34.4°C) in the average high-temperature. Throughout August, the nighttime temperature in Simpson averages to a pleasant 73.2°F (22.9°C).

Heat index

The heat index value during August is evaluated at a life-threatening hot 122°F (50°C). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As body temperatures escalate without effective heat release, one might face dehydration threats.
