The heat index value for August is estimated at a tropical 86°F (30°C).

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 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly meaningful for babies and toddlers.
