Weather in August
Temperature
In August, the average high-temperature registers at a still moderately hot 82.2°F (27.9°C), nearly identical to July's 83.7°F (28.7°C). Nightly temperatures drop to an average low of 64.6°F (18.1°C) in August.Heat index
August's average heat index is appraised at a tropical 89.6°F (32°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Note that heat index values are valued for light wind and location in the shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
