Weather in September
Temperature
Carter Nine observes a small decrease in the average high-temperature with the arrival of September, falling from August's tropical 90.3°F (32.4°C) to a warm 82.8°F (28.2°C). During September, the nighttime temperature averages to a refreshing 63.7°F (17.6°C).Heat index
The average heat index in September is estimated at a tropical 87.8°F (31°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
