Weather in August
Temperature
August commences with an average high-temperature of a still moderately hot 83.3°F (28.5°C), showing little deviation from July's 85.3°F (29.6°C). Throughout the month of August, Percival witnesses an average temperature of 64°F (17.8°C).Heat index
August's heat index is calculated to be a tropical 91.4°F (33°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.The metrics for the heat index are tailored for both shady environments and light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially crucial for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
