Weather in September
Temperature
The shift from August to September includes a minor decrease in the average high-temperature, lightly dropping from a hot 87.4°F (30.8°C) to a moderately hot 81.7°F (27.6°C). Throughout September, an average nighttime temperature of 60.6°F (15.9°C) is experienced.Heat index
September's heat index is appraised at a tropical 86°F (30°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Consider that heat index readings are for situations in the shade and light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', comes about by integrating the temperature readings with the humidity levels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
