Weather in August
Temperature
The transition from July to August brings an average high-temperature of a still moderately hot 84.4°F (29.1°C), barely different from July's 85.6°F (29.8°C). During the month of August, the temperature generally drops to a low average of 65.8°F (18.8°C).Heat index
The average heat index in August is appraised at a very hot 95°F (35°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Shun overexposure. Protection from sun ravages is indispensable. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
