Weather in August
Temperature
August brings an average high-temperature of a still moderately hot 80.6°F (27°C), showing a slight difference from July's 81.9°F (27.7°C). August nights are marked by an average temperature drop to a comfortable 65.3°F (18.5°C).Heat index
For August, the heat index is estimated at 84.2°F (29°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.The standards for the heat index are set for locations in shade and under light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
