September offers a sigh of relief to Laoag City, with rainfall amounts beginning to decrease. With the highest average high temperature in the year lurking at 30.9°C (87.6°F), September signifies the phasing out of the wet season. The gradual transition in the weather pattern, coupled with the reduced rainfall, gives the city an improved outdoor ambiance. As the city moves into October, a further decrease in rainfall and cooler temperatures is anticipated. September, serving as a threshold between the wet and dryer months of the year, promises a gradual amalgamation of favorable weather conditions.

Temperature

A minimal variation is noted in Laoag City's average high-temperature at the onset of September, reaching a still warm 29.5°C (85.1°F) from August's 29.4°C (84.9°F). September nights anticipate an average temperature of 25.2°C (77.4°F), a modest decline from the daytime.

Heat index

September's average heat index is estimated at a sweltering 36°C (96.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, 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 for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
