"Winds are expected to blow from the southwest or west, which could limit transport of smoke haze to Singapore," the agency said, adding that expected showers over Singapore and the surrounding region could help with haze conditions. The winds are expected to continue blowing from the southwest or west on Monday and Tuesday. "With showers expected over Singapore and the vicinity, the haze situation is likely to improve," said NEA.

NEA has advised the public to refer to the 24-hour PSI forecast when planning outdoor activities and to check the latest 1-hour PM2.5 readings before undertaking immediate outdoor activities.

When hourly 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.

For Sunday, NEA advised healthy individuals to reduce prolonged or strenuous outdoor physical exertion, while elderly people, pregnant women and children should minimise such activities.

People with chronic heart or lung disease should avoid prolonged or strenuous outdoor physical exertion.
