Weather in September
Temperature
September brings a slight decrease in the average high-temperature, shifting from a tropical 88°F (31.1°C) in August to a moderately hot 82.6°F (28.1°C). In the month of September, Gulf records a consistent average low-temperature of 64°F (17.8°C).Heat index
In September, the average heat index is calculated to be a tropical 89.6°F (32°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Always consider that heat index estimations are for light winds and places in the shade. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
