The haze in Singapore climbed into the unhealthy range on Monday afternoon as the three-hour Pollutant Standards Index (PSI) hit 111 at 4pm.
The PSI reading first crossed the 100 mark at 3pm, when it was recorded at 105.
According to the National Environment Agency (NEA) website, PSI readings of 50 and below denote "good" air quality, "moderate" for 51-100 and "unhealthy" for 101-200.
The PSI reading has been rising steadily on Monday.
At 2pm, the PSI reading was 100, up from 95 at 1pm and 80 at noon.
The last time the PSI went over 100 was on October 21, 2010, when it hit 106.
Under NEA's health advisory, those with existing heart or respiratory ailments should reduce physical exertion and outdoor activity while the general population should reduce vigorous outdoor activity when the PSI reading reaches unhealthy levels.
