Weather in August
Temperature
August's arrival shows an average high-temperature of a still tropical 91.4°F (33°C), hardly different from the previous month. During August, the nighttime temperature averages to a pleasant 70.5°F (21.4°C).Heat index
In August, the heat index is evaluated at a life-threatening hot 113°F (45°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

In August, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.Note: The daily high UV index of 6 during August translates into the following recommendations:
Fend off overexposure. Sun protection is vital. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
