Weather in August
Temperature
The advent of August brings an average high-temperature of a still warm 81.7°F (27.6°C), exhibiting minor difference from the previous month. August nights are marked by an average temperature drop to a comfortable 64°F (17.8°C).Heat index
Throughout August, the heat index is calculated to be a tropical 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
