September, the first month of the autumn in Ambulong, is still a warm month, with temperature in the range of an average high of 29.6°C (85.3°F) and an average low of 23.4°C (74.1°F).

Temperature

September's beginning signals an average high-temperature of a still moderately hot 29.6°C (85.3°F), barely different from August's 29.8°C (85.6°F). September nights experience a consistent temperature drop to a still warm 23.4°C (74.1°F).

Heat index

The average heat index in September is calculated to be a torrid 38°C (100.4°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 largely significant for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

July and September, with an average relative humidity of 87%, are the most humid months.
