Weather in August
Temperature
The shift into August reveals an average high-temperature of a still tropical 91°F (32.8°C), closely mirroring July's climate. In the month of August, the nighttime temperature dips to a steady average of 72.3°F (22.4°C).Heat index
August's mean heat index is evaluated at a burning hot 113°F (45°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
