Weather in September
Temperature
With the onset of September, Gibbon's climate undergoes a slight change as the average high-temperature moves from a tropical 91.9°F (33.3°C) in August to a warm 83.7°F (28.7°C). Gibbon records a mean low-temperature of 64.9°F (18.3°C) in September.Heat index
The heat index for September is estimated at a tropical 87.8°F (31°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Always consider that heat index estimations are for light winds and places in the shade. 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 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
