Weather in September

The first month of the autumn, September, is still a warm month in Butong, Philippines, with an average temperature varying between 29.7°C (85.5°F) and 24°C (75.2°F).

Temperature

Butong experiences a subtle adjustment in high-temperatures to a still moderately hot 29.7°C (85.5°F) with the onset of September, maintaining near parity with August's 29.8°C (85.6°F). Throughout the month of September, the nighttime temperature dips to an average of 24°C (75.2°F).

Heat index

For most parts of September, the heat index is computed to be a torrid 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: An average maximum UV index of 7 in September leads to these recommendations:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
