Weather in August
Temperature
July and August mark Marrero's peak of temperatures, averaging a high-temperature of 89.4°F (31.9°C).Heat index
The heat index in August is appraised at a blisteringly hot 105.8°F (41°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

However, keep in mind that shade structures may not provide full sun protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
