Weather in August
Temperature
The transition from July to August sees average high-temperatures adjusting to a still tropical 87.4°F (30.8°C), from a not significantly different 88.3°F (31.3°C). Nighttime temperature dips to a mean of 68.2°F (20.1°C) during August.Heat index
The heat index value during August is estimated at a sweltering 100.4°F (38°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Prevent overexposure. Protection from the sun's harmful effects is needed. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
