Weather in August
Temperature
The advent of August denotes an average high-temperature of a still warm 82.9°F (28.3°C), subtly different from July's 85.1°F (29.5°C). August nights are marked by an average temperature drop to an enjoyable 65.8°F (18.8°C).Heat index
The heat index in August is computed to be a tropical 89.6°F (32°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
