Singaporeans Can Breathe Easier as Haze Subsides
Singapore, known for its usually clear skies and fresh air, experienced a brief downturn in air quality recently due to the arrival of haze from neighboring countries. However, there is good news on the horizon as the National Environment Agency (NEA) anticipates an improvement in air quality in the coming days. Here’s what you need to know about the situation and what Singaporeans can expect.
Favorable Wind Patterns Reduce Haze Risk
One of the key factors contributing to the improved air quality in Singapore is the favorable wind direction. The NEA has reported that prevailing winds are expected to blow primarily from the east, lowering the likelihood of transboundary haze affecting the island nation. This is a positive development, as winds carrying haze from neighboring countries have been a primary cause of air quality issues in Singapore.
Anticipated Rainfall to Clear the Air
In addition to the beneficial wind patterns, Singapore is also expected to receive much-needed rainfall. The NEA forecasts showers over Singapore and the surrounding region. Rainfall can help to cleanse the atmosphere of haze particles, leading to improved air quality. While rain alone may not completely eliminate haze, it is a significant contributing factor to the reduction of haze levels.
Haze Situation Improves Despite Dry Conditions
Singapore experienced a temporary decline in air quality on Saturday, with air quality falling into the unhealthy range for the first time since 2019. Dry conditions over most parts of Singapore and the surrounding region had contributed to this deterioration. However, despite these challenges, the haze situation improved on Sunday.
Hot Spot Reduction Offers Hope
One positive indicator is the decrease in the number of hot spots in the region. On Sunday, the NEA reported a total of 68 hot spots, mainly located in the southern and central parts of Sumatra. This is a notable reduction compared to the 188 hot spots detected on Saturday. These hot spots are often indicative of forest fires, which can release haze into the atmosphere.
Air Quality Monitoring and Health Precautions
As of 11 pm, the 1-hour PM2.5 concentration readings in Singapore were within the normal range. The Pollutant Standards Index (PSI) ranged from 54 to 73, categorizing air quality as moderate. The NEA expects the PSI for the next 24 hours to remain in the moderate range.
It’s essential to remember that the health impact of haze depends on various factors, including an individual’s health status, the PSI level, and the duration and intensity of outdoor activities. The NEA advises the public to monitor 1-hour PM2.5 concentration readings and follow personal health guidelines when engaging in immediate outdoor activities.
For those planning outdoor activities for the following day, the 24-hour PSI forecast and corresponding health advisories provided by the NEA can help in making informed decisions about venturing outdoors.
As Singaporeans await the expected rainfall and improved air quality, it’s important to stay informed and follow the guidance provided by the NEA to ensure their health and well-being during this period of haze reduction.
