Today, smog continues to haze Singapore. As of 11 a.m., Singapore's air quality index is 194, which is still at an “unhealthy” level, making it the second-most polluted city in the world. According to information, Singapore's air quality has been at an “unhealthy” level since October 4. The smog and haze in Singapore is mainly affected by factors such as the continued spread of wildfires in Indonesia. Indonesian officials recently said that due to the El Niño phenomenon, wildfires broke out in parts of Kalimantan and Sumatra, causing a large amount of smog — and the fires may burn until November.
