Weather in August
Temperature
The arrival of August records an average high-temperature of a still warm 83.8°F (28.8°C), closely related to the 84.7°F (29.3°C) observed in July. August presents a pronounced difference from daytime highs, with a consistent average low-temperature of 62.1°F (16.7°C).Heat index
For August, the heat index is computed to be a hot 91.4°F (33°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
