Pila, Philippines

The transition into September brings an average high-temperature of a still moderately hot 29.9°C (85.8°F) that remains consistent with August. Throughout the nights in September, an average low-temperature of 24.5°C (76.1°F) is noted.

Heat index

September's average heat index is appraised at a very hot 38°C (100.4°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
