SINGAPORE: After two

As of 11am, the reading in the east, at 56, was in the second band (56-150), above the normal range.

Readings in the north, west, south and central areas were in the normal range.

The Pollutant Standards Index (PSI) for the next 24 hours is forecast to be in the moderate range for all regions, according to data from the National Environment Agency (NEA).

On Saturday, Singapore's air quality fell into the unhealthy range for the first time since 2019, as winds brought haze from Indonesia's forest fires.

In its daily haze advisory on Monday evening, NEA had forecast a low likelihood of haze on Tuesday,.

It had said that wetter conditions were observed over many parts of the surrounding region on Monday.

The health impact of haze is dependent on one’s health status, the Pollutant Standards Index (PSI) level, and the length and intensity of outdoor activity. NEA regards a PSI reading of 101-200 as "unhealthy".

For immediate outdoor activities, members of the public should check the 1-hr PM2.5 concentration readings and personal guide. A reading of between 56 and 150 is considered elevated.

The 24-hour PSI forecast and corresponding health advisories can be used when planning next-day outdoor activities.

On Saturday, Minister for Sustainability and the Environment Grace Fu said that Singapore has enough masks for use if the haze worsens.

"We have been planning for that," she said, when asked about preparations to make masks available. "I believe that we have sufficient stock for us. But of course, it's always important to remember that we're dealing with uncertain weather conditions."

Ms Fu added that if necessary, Singapore will acquire more masks.

According to the interagency haze task force, N95 masks are not required for short exposure such as commuting from home to school or work.
