September, the first month of the autumn in Tarzan, is also a hot month, with an average temperature fluctuating between 86°F (30°C) and 67.1°F (19.5°C).

Temperature

As September commences, the average high-temperature subtly reduces, transitioning from 94.6°F (34.8°C) in August to a still hot 86°F (30°C). During the month of September, the nighttime temperature falls to an average of 67.1°F (19.5°C).

Heat index

In September, the heat index is computed to be a hot 89.6°F (32°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.
Know that the heat index computations account for shaded terrains and slight winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
