Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 90°F (32.2°C) in August to a moderately hot 83.7°F (28.7°C). During the nights in September, Catoosa experiences a consistent average temperature of 63.5°F (17.5°C).Heat index
The heat index value for September is evaluated at a tropical 89.6°F (32°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.The standards for the heat index are set for locations in shade and under light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
