Weather in August
Temperature
The shift to August signals an average high-temperature of a still tropical 90.7°F (32.6°C), subtly varied from July's 91.8°F (33.2°C). Commerce records a consistent low-temperature of 72.1°F (22.3°C) during August nights.Heat index
For August, the heat index is calculated to be a burning hot 113°F (45°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

May through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for average individuals.Note: In August, an average UV index of 7 transforms into the following instructions:
Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
