Weather in August
Temperature
The beginning of August records an average high-temperature of a still moderately hot 82.2°F (27.9°C), marking a negligible difference from July's 83.8°F (28.8°C). Throughout August, an average low-temperature of 63.7°F (17.6°C) is experienced.Heat index
In August, the heat index is appraised at a tropical 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
