Air quality in S'pore still unhealthy despite rain

SINGAPORE - Heavy rains did not improve the hazy conditions in Singapore on Tuesday, Sep 15, as the air quality remained in the "unhealthy" range.

Despite heavy showers with gusty winds over many areas of Singapore in the late morning and early afternoon, the 24-hour Pollutant Standard Index (PSI) was between 114 and 138 as of 8pm, according to the National Environment Agency (NEA).

A 24-hour PSI reading of between 101 and 200 is considered to be within the unhealthy range.

Meanwhile, the three-hour PSI at 8pm was 112, a further improvement from the previous reading of 117 at 7pm, following a reading of 137 recorded at 4pm.

In a statement on Tuesday evening, NEA said that hazy conditions can still be expected on Wednesday, Sep 16, and the air quality could deteriorate further due to unfavourable winds blowing in denser haze from Sumatra. NEA added that the 24-hour PSI may enter the low section of the "very unhealthy" range (between 201 and 300).

The current haze situation has forced a number of schools to cancel or move outdoor activities indoors.

However, the Singapore Grand Prix organisers clarified in a statement that the racing and entertainment activities during the upcoming race weekend on Sep 18-20 will proceed as planned for now.

With the present air quality forecast, healthy people are advised to reduce prolonged or strenuous outdoor physical exertion, according to NEA's health advisory. The elderly, pregnant women and children should minimise outdoor activities, while persons with chronic lung or heart disease should avoid outdoor activities.
