Weather in August
Temperature
The shift from July to August is characterized by an average high-temperature of a still warm 81.1°F (27.3°C), not significantly different from the 81.5°F (27.5°C) of July. August brings with it a nighttime average temperature of 62.8°F (17.1°C).Heat index
Throughout August, the heat index is evaluated at a tropical 86°F (30°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Observations indicate that the heat index values are for shady locations with light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
