Weather in August
Temperature
The advent of August observes an average high-temperature of a still moderately hot 84°F (28.9°C), nearly identical to July's 85.3°F (29.6°C). August witnesses an average low-temperature hovering around a refreshing 65.7°F (18.7°C).Heat index
For most parts of August, the heat index is estimated at a tropical 93.2°F (34°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
