Weather in September
Temperature
September's onset records an average high-temperature of a moderately hot 82°F (27.8°C), a near match to August's 86.5°F (30.3°C). Manila witnesses a consistent average low-temperature of 64°F (17.8°C) throughout September.Heat index
In September, the heat index is calculated to be a tropical 87.8°F (31°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Consider that heat index readings are for situations in the shade and light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. 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. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
