Weather in September
Temperature
The arrival of September brings an average high-temperature of a still moderately hot 28.2°C (82.8°F), closely following the temperature pattern of August. During September, Buna records a consistent average nighttime temperature of 19.5°C (67.1°F).Heat index
The average heat index in September is computed to be 29°C (84.2°F). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes.
