Weather in August
Temperature
The arrival of August records an average high-temperature of a still moderately hot 81.9°F (27.7°C), closely related to the 83.8°F (28.8°C) observed in July. August nights observe an average temperature dip to a refreshing 62.2°F (16.8°C).Heat index
The average heat index in August is estimated at a tropical 87.8°F (31°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
