Weather in August
Temperature
The initiation of August sees an average high-temperature of a still moderately hot 82°F (27.8°C), showing minor variations from the previous month. In August, the average low-temperature records at a refreshing 64.9°F (18.3°C) during the nights.Heat index
August's average heat index is estimated at a hot 87.8°F (31°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
