Weather in August
Temperature
August registers an average high-temperature of a still warm 81.1°F (27.3°C), slightly varied from July's 82°F (27.8°C). During August, the nighttime temperature averages to a refreshing 64°F (17.8°C).Heat index
The heat index value during August is computed to be a tropical 86°F (30°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
