Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from a tropical 88.2°F (31.2°C) in August to a moderately hot 81.3°F (27.4°C). In September, the average low-temperature is a refreshing 61.9°F (16.6°C).Heat index
In September, the average heat index is evaluated at a tropical 86°F (30°C). Long-standing exposure and activity could induce a feeling of tiredness and lead to heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
