Weather in August
Temperature
August's onset brings an average high-temperature of a still warm 81.3°F (27.4°C), showing a minute difference from July's 82.9°F (28.3°C). An average nighttime temperature of 59.9°F (15.5°C) is noted during the month of August.Heat index
In August, the average heat index is computed to be a hot 86°F (30°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
