Haze conditions in Singapore are expected to improve as inter-monsoon conditions set in, with light and variable winds reducing the likelihood of smoke haze being transported from fires in the region, the Meteorological Service Singapore said on Oct 29. Showers are expected over Sumatra, Kalimantan, Singapore and the surrounding region on Oct 30, which should help suppress the haze, the National Environment Agency said. The 24-hour Pollutant Standards Index (PSI) was in the good to moderate range across Singapore on Oct 29, with PM2.5 levels mostly in the normal range despite a brief rise in the west.
Inter-monsoon conditions have been progressively setting in with the weakening of the southwest monsoon, which had brought persistent southeasterly or southwesterly winds that transported smoke haze to Singapore. Air quality reached 'unhealthy' levels for seven days and 'very unhealthy' levels for three days between Oct 16 and Oct 28. Moderate to heavy thundery showers are expected over parts of Singapore on most afternoons in the first two weeks of November, with total rainfall slightly above average.
