Weather in August
Temperature
Allandale notes an average high-temperature of a still warm 81.9°F (27.7°C) in August, displaying minor variation from July. During the month of August, an average low-temperature of 63.1°F (17.3°C) is recorded.Heat index
August's mean heat index is estimated at a tropical 87.8°F (31°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
