Weather in August
Temperature
With the advent of August, Herald experiences an average high-temperature of a still warm 82°F (27.8°C), mirroring a close resemblance to the previous month. Nightly readings in August display a noticeable downturn from daily highs, with the average low-temperature registering a refreshing 59.4°F (15.2°C).Heat index
Throughout August, the heat index is evaluated at a tropical 87.8°F (31°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
