Weather in September
Temperature
Alangilan's weather, upon September's arrival, documents an average high-temperature of a still moderately hot 29.3°C (84.7°F), nearly the same as the prior month. Alangilan experiences a minimal drop from daytime high temperatures, recording an average low-temperature of 24.3°C (75.7°F) throughout September.Heat index
Throughout September, the heat index is calculated to be a sweltering 37°C (98.6°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Consider that heat index readings are for situations in the shade and light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
Humidity
September and October, with an average relative humidity of 84%, are the most humid months.Rainfall
The month with the most rainfall is September, when the rain falls for 21.2 days and typically aggregates up to 105mm (4.13") of precipitation.Daylight

Sunshine
In September, the average sunshine is 8.4h.UV index
February through June, August and September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.Note: In September, the maximum UV index of 7 translates into these guidelines:
Take precautions against overexposure. Protection against sun damage is needed. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
