This morning, the three-hour PSI reading rose to 34 at 11 am but PSI levels 50 and below remain in the “good range”.
A National Environment Agency (NEA) spokesman told The Straits Times (ST), heavy rain over Singapore and Sumatra – including parts of the Riau province and the Strait of Malacca – on Saturday, contributed largely to the clearer skies yesterday.
But the haze, caused by forest fires in Indonesia, may persist for the next two days if the burning goes on, said the NEA.
Deputy head of the geography department at the National University of Singapore Matthias Roth suggested that winds blowing from other directions – not just Indonesia – towards Singapore could have helped lessen the haze over the weekend as well.
He told ST, the “hot spot count” may have reduced over the last few days, but added, “this, however, is difficult to verify because forest fires cannot be detected by satellites during cloudy or overcast conditions.”
More than 10,000 people continued to participate in the Nike City 10K run yesterday morning, reported Today. The PSI was below 40 till noon.
Many told the paper they felt the haze had little impact on their performance.
The lowered PSI readings also brought families out on Saturday . Many spent the day outdoors at East Coast Park while Orchard Road was packed with shoppers.
Over at Suntec City, the Canon PhotoMarathon also saw 1,700 people participating, while S-League matches resumed after some games were postponed due to the high PSI level.
However, some businesses continue to be affected by the haze. Owner of My3Wheels Andrew Kung, 39, told The Sunday Times his trikke – a three-wheel cambering vehicle – business was down 80 per cent compared to last weekend.
