"For tomorrow, the haze situation over Singapore is expected to remain subdued due to showers over Sumatra, Kalimantan and Singapore and the surrounding region," said NEA on Sunday. "While the prevailing winds are expected to blow from the east or southeast on Tuesday and Wednesday, forecast showers are likely to keep the haze situation suppressed."

NEA advises the public to use the 24-hour PSI forecast when planning outdoor activities and check the latest 1-hour PM2.5 readings for immediate activities.

When 1-hour PM2.5 concentrations are in the elevated band, healthy individuals should reduce strenuous outdoor activities for the next hour.

Vulnerable groups, including children, elderly people, pregnant women and those with chronic heart or lung conditions, should avoid strenuous outdoor activities during that period.
