Weather in August
Temperature
The advent of August brings an average high-temperature of a still tropical 88°F (31.1°C), exhibiting minor difference from the previous month. Despite higher daytime temperatures, nighttime averages fall to a fresh 54.1°F (12.3°C) in August.Heat index
Throughout August, the heat index is evaluated at a tropical 93.2°F (34°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
