Weather in August
Temperature
The arrival of August marks a slight shift to an average high-temperature of a still tropical 89.8°F (32.1°C) from July's 90.3°F (32.4°C). During the nights in August, the temperature averages to a moderately hot 73.6°F (23.1°C).Heat index
The average heat index in August is evaluated at a blistering 109.4°F (43°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.One should consider that heat index numbers are for shaded settings and light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for average individuals.Note: A daily maximum UV index of 7 in August translates into the following instructions:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Boost your sun resistance with garments that are densely woven yet spacious.
