Weather in September
Temperature
September's arrival aligns with a minor decrease in average high-temperatures, from August's tropical 91°F (32.8°C) to a moderately hot 83.1°F (28.4°C). Nighttime temperatures hover around an average low of 64°F (17.8°C) in September.Heat index
During September, the heat index is estimated at a hot 86°F (30°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Heat index determinations are made taking into account the shade and light air movements. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. 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. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
