The 3-hour Pollution Standards Index (PSI) in the city-state rose to 102 at 4 p.m. local time (0800 GMT). A PSI reading above 100 indicates air pollution has reached an “unhealthy” level.
The PSI level in the island-nation hit a record-high of 401 in June 2013, when smoke from forest burning in Indonesia engulfed the city.
