Weather in August
Temperature
August, known for its average high temperature of 28.8°C (83.8°F) and an average low temperature of 15.2°C (59.4°F), is the warmest month.Heat index
August's mean heat index is calculated to be a tropical 31°C (87.8°F). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
