Weather in August
Temperature
The advent of August observes an average high-temperature of a still warm 83.8°F (28.8°C), nearly identical to July's 84.6°F (29.2°C). August nights are characterized by a notable drop from daytime highs, with an average low-temperature of 61.2°F (16.2°C).Heat index
For August, the heat index is computed to be a tropical 91.4°F (33°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical 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.
