Weather in September
Temperature
The commencement of September involves a temperature shift, with the average high-temperature dropping from a very hot 96.8°F (36°C) in August to a tropical 87.8°F (31°C). In the month of September, Avoca's average low-temperature falls to a pleasant 68.9°F (20.5°C).Heat index
September's average heat index is calculated to be a tropical 93.2°F (34°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
