Weather in September
Temperature
The advent of September observes an average high-temperature of a moderately hot 82°F (27.8°C), nearly identical to August's 86.5°F (30.3°C). Gibson experiences a steady low-temperature of 63.3°F (17.4°C) throughout September.Heat index
September's mean heat index is evaluated at a tropical 87.8°F (31°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
