Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a moderately hot 82.8°F (28.2°C), showing little divergence from the previous month's conditions. During September, Comfort records an average temperature of 67.6°F (19.8°C) at night.Heat index
The heat index in September is computed to be a hot 89.6°F (32°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
