It's very hazy. The air quality according to the National Environment Agency says it is "Unhealthy". People are advised to stay indoors, and that's what I did.
This picture is taken this morning. When the PSI was around 130.
It did turn better during the day, but now it is worse. The PSI is now 150.
Anyone interested can monitor it via the NEA website at: http://app.nea.gov.sg/psi/
Looks like my electricity bill will be super high. The air conditioning and fileter has been running non stop since yesterday.
