September weather forecast
Limay, Philippines

September, the first month of the autumn in Limay, is still a warm month, with temperature in the range of an average low of 24.9°C (76.8°F) and an average high of 29.5°C (85.1°F).

Temperature

The transition from August to September sees average high-temperatures adjusting to a still moderately hot 29.5°C (85.1°F), from a not significantly different 29°C (84.2°F). Nighttime temperature sees a small decrement from daytime highs, dipping to an average of 24.9°C (76.8°F) during September.

Heat index

The heat index for September is computed to be a torrid 37°C (98.6°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

UV index

The months with the highest UV index are January through June, September through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the ordinary person.
Note: A typical high UV index of 7 in September suggests the following recommendations:
Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. 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. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
