Plombokan's September showcases an average high-temperature of a tropical 30.3°C (86.5°F), hardly distinct from August's 29.3°C (84.7°F). In Plombokan, an average low-temperature of 21.5°C (70.7°F) is recorded during September nights.

Heat index

September's average heat index is estimated at a torrid 37°C (98.6°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
