September weather forecast
Del Monte, Philippines

The first month of the autumn, September, is still a hot month in Del Monte, Philippines, with an average temperature fluctuating between 30.5°C (86.9°F) and 24.8°C (76.6°F).

Temperature

The advent of September reveals an average high-temperature of a still hot 30.5°C (86.9°F), showing minimal difference from the prior month. Nightly temperatures drop to an average low of 24.8°C (76.6°F) in September.

Heat index

Throughout September, the heat index is evaluated at a blisteringly hot 40°C (104°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Data suggests that the heat index is set for environments in shade and with a light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

August and September, with an average relative humidity of 81%, are the most humid months.

Rainfall

In September, in Del Monte, the rain falls for 21 days. Throughout September, 128mm (5.04") of precipitation is accumulated. In Del Monte, during the entire year, the rain falls for 185 days and collects up to 830mm (32.68") of precipitation.

UV index

February through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.
Note: The UV index of 7 in September translates into these instructions:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
